Flower urchin trembles with danger

Flower urchin looks like a lovely ball of trembling flowers. However, those flowers contain highly toxic venom. This sea urchin’s maximum diameter is about 15 centimeters. It lives in areas of sand and rubble along coral reefs. It also inhabits areas of sea grass.

Beauty to Avoid

Although commonly known as the Flower urchin, the scientific name of this echinoderm is Toxopneustes pileolus. The genus name Toxopneustes means “poison breath.” And “skullcap” is the meaning of pileolus, the species name. These names underscore the creature’s deadly possibilities.

Its toxins can cause a number of symptoms. These include breathing problems, muscular paralysis, and numbness. Such effects can render the victim disoriented. The combination can result in accidental drowning. Initial contact gives the victim an extremely painful shock. Then numbness and spasms start to travel through the body from the point of contact. Happily, accidental contact with this sea urchin is extremely rare.

Deceptive Flowers

Various projections cover a Flower urchin’s exposed surface. The most noticeable are the flower-like pedicellariae. These colorful appendages are actually jaws. Each jaw has three prongs. Moreover, the flower-like jaws have sensors that detect contact or proximity movement to the sea urchin. Any touch will trigger the jaws to contract. Then the jaws inject venom. To make matters worse, once the jaws are triggered, they can easily break free from the sea urchin. That means they stay embedded and will continually inject venom for several hours.

The flowers of this sea urchin can appear a pinkish or yellowish white. There will be a single lavender dot in the middle. These false flowers typically cover the short spines of the urchin.   

On the underside of the Flower urchin are double rows of tubular feet. These emerge along the ten segments of the urchin’s shell. In the center is the creature’s mouth, which contains five plates. These plates function as teeth that crunch food. Sea urchins forage along the bottom on algae, bryozoans and detritus. With the mouth facing the substrate, the anus faces the water column and any curious passing diver.

Flower Urchin Piled with Debris

To observe a Flower urchin, divers must keep a safe distance. Careful observation of the surface of this creature shows thin, translucent, and waving appendages that are longer that the trembling flowers of the urchin. These appendages are tubular feet that end in three claws. These are used to clear the urchin’s surface of debris.

Toxopneustes pileolus
Appendages of Toxopneustes pileolus

However, the urchin also uses these tubular feet to move debris from the substrate onto its top and sides. Scientists call this covering or heaping behavior. The tubular feet keep debris in place. The function or purpose of this behavior remains a mystery. Because divers think that a small heap of debris is simply rubble, most flower urchins remain unnoticed.

In the rare instances when we see a Flower urchin, our dive masters will warn guests first and then carefully show the beautiful creature. Afterwards, the dive master will use his stick to move debris on top of the urchin. This helps the urchin but also prevents accidental contact by anyone else passing by.

To dive with such caring dive masters, please make your trip reservations directly with Miguel’s Diving.  

Fin whale startles crew

Fin whale surfaced right next to one of our staff while he was fishing for yellowfin tuna. Tomini Bay where we dive is over four kilometers deep. So, large cetaceans are part of the marine environment in Gorontalo.

Surprise Encounter

Boka, one of Miguel’s Diving dive masters, headed to deep waters offshore. On his day off, he decided to fish for yellowfin tuna. Local fishermen use traditional handlines. This method is ecologically sustainable.

Identification book for whales

Suddenly, a large whale surfaced only a few meters away from his outrigger canoe. Then the whale exhaled, sending spray into the air.

Boka’s outrigger canoe measures five meters in length. He estimates the fin whale that surfaced next to him to be twelve meters. That means this particular whale was still small. Adult fin whales can reach 22 meters in length. This species is the second largest animal on planet earth, after the larger Blue whale. The cetaceans we see tend to be young. That includes whale sharks, orcas, and whales. It seems that the deep waters of Tomini Bay are a prime location for young cetaceans to grow into adults.

Fin Whale in the Southern Hemisphere

Although fin whales live in all the world’s oceans, they are mostly sighted in the southern hemisphere. When a fin whale surfaces, its dorsal fin appears right after the whale blows. The dorsal fin is quite small and points backwards. Its flukes are rarely visible. Most notable, it is large size. Also, fin whales ignore boats. This is what happened when Boka encountered one.

Fin whale sketch (c) NOAA

The fin whale used to be hunted commercially. This is now banned. As a result of over hunting, this species is considered endangered. The population of the southern hemisphere has been particularly slow to recover. Balaenoptera physalus is the scientific name.

Fin whales are filter feeders. Those in the southern hemisphere feed almost exclusively on krill. They can also eat plankton, small schooling fish, and squids. Their only known predator is the Orca or killer whale. In Gorontalo we see orca annually, usually in January and February.

Although scuba divers are not likely to see a fin whale in Gorontalo, whale shark sightings are common. So, please make your dive reservations directly with Miguel’s Diving.  

Yellow lace coral lives deep down

Yellow lace coral thrives below thirty meters in Gorontalo. Its bold honey-lemon hue adds distinctive color to deep reefs where ambient light is low.

Not a Reef Building Coral

Although they have some similarities, lace corals are not fire corals. Millepora fire coral species have symbiotic algae living inside their tissues. These algae contribute nutrients and color to fire corals, as well as reef building corals.

yellow lace coral
Deep water Yellow lace coral

However, lace corals are hydrocorals. Their skeleton is made of calcium and can easily break. Its tiny polyp pores are minute with diameters less than one millimeter. Lace corals have two genus, Stylaster and Distichopora. They lack symbiotic algae. This means that the distinctive colors of lace corals are part of their skeletons. Whereas other coral skeletons turn white when the colony dies, lace corals retain their coloration even after death.

Yellow Lace Coral & Deep Reefs

Divers in Gorontalo who venture down to thirty meters can easily spot Yellow lace corals on certain dive sites. These corals look like yellow fans. Sometimes, a colony has more than one fan from the single base. The branches are stout and rounded. Gorontalo’s Yellow lace corals have tips of white. They are found on vertical surfaces and tucked into small holes or crevasses.

The Yellow lace coral could be Distichopora violacea, despite not being purple. There are 34 named species of Distichopora, but many remain unnamed. They are only found in Pacific oceans, including Tomini Bay where we dive.

Tiny, Stinging Hairs

Distichopora stinging cells
Stinging hairs of Yellow lace coral

Like other Distichopora species but unlike reef building corals, our Yellow lace coral has different types of polyps. All connect via canals inside the yellow skeleton where they are imbedded. These microscopic polyps have different functions. Two types protrude from the skeleton. They are gastropores and dactylopores.

The dactylopores have fine hairs that possess stinging cells called nematocysts. They can leave stings on divers who touch or brush against them. The function of these cells is to sting plankton. The stunned plankton are then eaten by gastropores, which contain the feeding polyps.  

Complex Reproduction of Lace Corals

Distichopora cf violacea
Multiple Yellow lace coral colonies

Although reproduction among reef building corals is relatively straightforward, that of lace corals is not. Lace coral polyps release medusae, which look like microscopic jellyfish. These medusae possess both male and female reproductive organs. These in turn release eggs and sperm into the ocean. A fertilized egg will develop into a larvae that swims until it reaches a hard surface. There is will attach and form a new lace coral colony.

Lace corals can also reproduce by fragmentation. For your chance to see Gorontalo’s deep water Yellow lace coral, please make your dive reservations directly with Miguel’s Diving.  

Leopard sea cucumber self-mutilates

Leopard sea cucumber is a beautiful creature of the ocean floor. However, divers should avoid touching its sensitive body.

Spotted Beauty

The Leopard sea cucumber lives in the eastern Indian and the western Pacific oceans. In the areas we dive in Gorontalo, it can only be found dependably at a single dive site. This sea cucumber lives in sandy areas, flanked by coral reef. Researchers say that it lives from three to almost forty meters deep. We usually find it between 15 and 18 meters here.

Leopard spots
Close-up of spots

Although research claims it can grow to 60 centimeters, those in Gorontalo measure only half of that length. Divers can easily identify the Leopard cucumber. Its spotted pattern is distinctive and unmistakable. The tubular body is grey but sprinkled with random rows spots. These spots are orange and edged in brown.

Avoid Touching

Leopard sea cucumber is highly sensitive. It considers touching, grabbing, or lifting to be a threat. When threatened, it will eject white strings. These elongate in sea water. They also become sticky. Scientists consider this behavior to be defensive.

These white strings are called Cuverian tubes after the French zoologist who first studied them. They are naturally attached to the sea cucumber’s interior respiratory system. When the Leopard cucumber feels threatened, it will contract its body muscles. This contraction is so great that it tears the cucumber’s interior. The contraction forces Cuverian tubes out of its anus. In this way, it self-mutilates.

The Leopard sea cucumber can regrow its tubes. However, this takes several weeks. So, divers should avoid touching this sea cucumber. The tubes contain toxins, which can cause skin irritation in humans. Interestingly enough, researchers are using toxins from the Leopard sea cucumber in cancer research.

Leopard Sea Cucumber in Ecology

This sea cucumber has several rows of tubular feet on its underside. It moves slowly across the sandy bottom. While doing so, it ingests sand and anything the sand contains. In this way, all sea cucumbers clean the ocean floor of detritus and other waste materials.

Moreover, its own waste is beneficial to coral growth. After internal digestion, it excretes calcium carbonate and ammonia along with clean sand.

Home for a Fish

Pearl fish live inside of some Leopard sea cucumbers. The fish’s scientific name is Carapus mourlani. It enters and exits the cucumber via the anus, usually tail first. A scientific study in Indonesia of Bohadschia argus, the official name for the Leopard sea cucumber, found fifteen pearl fish living inside a single cucumber!

Sometimes an Emperor shrimp will be living on the sea cucumber’s surface.

Arothron caeruleopunctatus pufferfish hiding in plain sight

Arothron caeruleopunctatus is a large pufferfish that hid in plain sight until a Japanese researcher named it in 1994.

Not the Other Blue-spotted Puffer

Scientific names are always best to identify marine life. Although the name of the large puffer Arothron caeruleopunctatus means “blue-spotted,” another small pufferfish is often called the Blue-spotted puffer. That fish is a small toby named Canthigaster solandri. It has various blue spots and a colorful body. An internet search for a blue spotted puffer will produce photos for C. solandri, not A. caeruleopunctatus.

Arothron caeruleopunctatus

Arothron caeruleopunctatus can measure to 80 centimeters in length. That makes this species one of the largest pufferfishes worldwide. Divers giving it a casual glance would find it uninteresting. Its body is primarily dull with hues of gray and dark blue. Ventrally, it is often white. Dorsally, it can have a yellow, irregular blotch. The fish’s scientific name comes from the numerous blue to white spots found on its body. These are round to rice shaped. Also, concentric lines circle the fish’s eyes.

Unnoticed until 1994

Divers assumed that this oval-shaped fish was one of the other large puffers that live in Indo-Pacific waters. However, in 1994, Dr. Keiichi Matsuura published his finding of this pufferfish that had been hiding is plain sight. Dr. Matsuura is curator emeritus at the zoology department of the Museum of Nature and Science in Tsukuba, Japan.

In addition to Arothron caeruleopunctatus, he has discovered and named other pufferfishes. These include Arothron multilineatus (2016) from Ryukyu Islands, Japan, and Chelonodontops alvheimi (2018) from Myanmar. Also, he named a new Fugu puffer, Takifugu flavipterus (2017) from Japan, Korea, China, Taiwan, and Far East Russia. Another pufferfish he named is Canthigaster aziz (2020) from the northern Red Sea off Saudi Arabia.

Arothron caeruleopunctatus in Gorontalo

Divers can see this Blue-spotted puffer occasionally along Gorontalo’s coral reefs and deep walls. Like other large pufferfishes, it is quite shy around divers. Careful approach can reward a patient diver with a clear view of the blue-spotted pattern of this fish. It lives from two meters to below safe diving limits.

Smile for the camera!

A close look reveals that its skin lacks scales. Also, its dorsal and anal fins are small. These are located towards the back of its body and are symmetrical. Moreover, it lacks a pelvic fin. Its short snout has two pairs of nostrils. It feeds on invertebrates that live on the substrate. To feed, it uses its four strong teeth. This pufferfish is active during the day.

Thylacodes grandis captures plankton in its net

Thylacodes grandis, or the Grand Worm Sail, uses mucous like a net to capture plankton. Its beautiful batik-patterned head is unmistakable.

Grand Worm Snails in the Reef

Thylacodes grandis
The batik-patterned head of Thylacodes grandis

Worm snails are a family of marine molluscs. They live in long tubes rather than the usual coiled chambers of other snails. Worm snail tubes are irregular. Grand worm snails in Gorontalo measure about seven to ten centimeters in height. A worm snail will grow its tube from a hard substrate on the reef. Sometimes, a Grand worm snail will live separated from other marine life. More often, it will grow up among various corals with only its head above. Since these worm snails are long lived, hard corals can grow on the tubes.

Grand worm snails live in all Gorontalo’s coral dive sites. However, divers can easily overlook them. Most distinctive about this species is its lack of a cap. Also known as an operculum, the cap shuts the tube from the top, thus protecting the worm snail inside. Because it lacks this cap, the Grand worm snail’s head is exposed for divers to see. It has a distinctive maze of white to golden lines over a dark background. This background can be black to deep maroon. It resembles batik. Also apparent are the creature’s fleshy horns. When a diver approaches, the Grand worm snail will duck its head down into its tube.

Fishing with Mucous

Worm snails gather food by producing mucous steams. Their gills create a slight current. This current sends plankton, that floats in the water column, into its sticky mucous. A careful diver can watch as the Grand worm snail rotates its head and draws its mucous net into its mouth.

An easy way to search for worm snails in Gorontalo is simply to look for the mucous strands floating above the reef. The most common worm snail here is Dendropoma maxima. It grows from inside massive coral heads, often in groups. Since this species has a dark cap, divers can easily distinguish it from Thylacodes grandis. Grand worm snails in Gorontalo typically live below fifteen meters.

Thylacodes grandis and other names

Some older resources give the scientific name as Serpulorbis grandis. This is not an accepted name. Vermetus grandis is another unaccepted name associated with the Grand worm snail. Taxonomic work done in 2005 and 2006 has yet to be harmonized. However, there are over forty confirmed species in the Thylocodes genus. These include two new species, one in 2017 and another in 2018. The most beautiful and photogenic worm snail in Gorontalo is indeed Thylacodes grandis.

Banded Amphiscolops flatworms throw a party

Banded Amphiscolops flatworms are an undescribed species and rarely seen. However, during a check dive in Gorontalo, divers encountered dozens of them.

It’s a Party

Amphiscolops
Dozens of rare acoel flatworms

Miguel’s Diving staff has encountered this rare marine creature less than five times over the two decades we have dived Gorontalo’s biodiverse waters. In previous encounters, only three to five individuals were present. Those Banded Amphiscolops flatworms stayed on the same coral head for several weeks before disappearing from view. They never returned to that spot. In November, 2022, divers from HobbyDive Jakarta were delighted at such a rare encounter. The mystery remains as to why so many of these flatworms gathered. A close inspection of a photo taken during the dive clearly shows them grazing. What they are eating is unclear. However, researchers know that other species of acoel flatworms feed on detritus, diatoms, and tiny crustaceans, especially copepads.

Banded Amphiscolops flatworms

Flatworms are bilaterally symmetrical. Plus, their bodies are soft and flattened, hence the name. Typically, microscopic cilia will protrude from their skin. These are movable hairs. Those on the ventral or underside of the flatworm will move the creature along.

three banded ones
Banded Amphiscolops flatworms

Amphiscolops is a genus of acoel flatworms. Acoel derives from Greek words that mean “no cavity.” Acoel flatworms lack a fluid-filled body cavity. Also, they lack respiration. However, species do have various sensory organs that can only be detected by microscope. Acoel flatworms reproduce via two methods, depending on the species. Most can reproduce by fragmentation. When part of this type of flatworm breaks off, it will grow to become a separate individual. Other acoel flatworks can reproduce sexually.

Since Banded Amphiscolops flatworms are an undescribed species, no one yet know how they reproduce. No one knows why they suddenly congregated in numbers, only to disappear again. When an Amphiscolops flatworm stretches out, its head will be obvious since its tail will appear slightly forked. In the photos we have of Banded Amphiscolops flatworms, they usually appear rounded with their edges rolled in. Perhaps this is part of their feeding behavior. However, close inspection of individuals reveals the slightly forked tail. The end that is not forked will be the head.

It measures about five millimeters in length. A search of online photographs shows the banded flatworm in Halmahera, Indonesia and Aniloa, Philippines. A body diagram of a different Amphiscolops found in Myanmar is available at this link.   

Only with Miguel’s Diving

Only Miguel’s Diving guests see such rare sights in Gorontalo. We have the experience and knowledge to find and explain. So, please make your dive reservations with us.  

Ecsenius yaeyamaensis scatters in Gorontalo

Ecsenius yaeyamaensis, or the Yaeyama combtooth blenny, lives in only a few dive sites in Gorontalo. Miguel’s Diving staff know where to show divers this delightful fish.

How to identify Ecsenius yaeyamaensis

Ecsenius yaeyamaensis
The distinct markings of Ecsenius yaeyamaensis

The best way to determine if a pale combtooth blenny is E. yaeyamaensis is to check for a black chin strap. Then look for a black “Y” or “V” mark behind the strap marking. The fish will also have a couple of rows of black dashes behind its eyes. The body will have rows of indistinct white spots.

Only one other combtooth blenny looks similar to Ecsenius yaeyamaensis. That fish is E. strictus, which lacks the black markings, and is endemic the Australia’s Great Barrier Reef. However, the Yaeyama blenny can be found through out Indo-West Pacific area from Sri Lanka north to Taiwan. This includes Japan’s Yaeyama archipelago where the fish was first discovered in 1954. Its range stretches to Australia and Micronesia.

Cute Combtooth Blennies

Combtooth blennies number over 400 described species in 58 genera. Divers can recognize them by looking at their behavior. Most lack a bladder that allows other fishes to swim in the water column. So, combtooth blennies will perch on the bottom. Enlarged pectoral fins allow them to sit on coral or sand.

Moreover, divers can easily recognize them by looking at their bodies. Typically, a combtooth blenny will have a blunt head and large eyes. Its dorsal fin is continuous. Also, many species have cirri that stick out between their eyes. However, those of Ecsenius yaeyamaensis are too small and pale to be noticed.

This type of blenny lacks teeth. Instead, their dental plates are like combs. These fish will use their comb-like dental plates to scrape algae and other food off rocks and coral. Combtooth blennys also lack scales.

A rarity in Gorontalo

Yaeyama combtooth blenny perches on coral

The Yaeyama combtooth blenny lives in small, scattered colonies in Gorontalo. It will be in areas where other combtooth blennies live. However, its generally pale complexion makes it tricky to spot. Since its maximum length is six centimeters, its small size makes hiding from divers easy. Miguel’s Diving is the only operator in Gorontalo aware of this cute fish.

Polydorella spionid worms whip their food

Polydorella spionid worms crowded the upper surface of a sponge. Their feeding activity caught the attention of a Miguel’s Diving staff. Since they are super tiny, the sponge seemed to be covered by wiggling hairs.

A Mystery Solved

With such rich marine life, the reefs of Gorontalo are truly a hidden paradise. Despite operating since 2003, our staff had never noticed Polydorella spionid worms. They typically live on the surface of sponges of which Gorontalo has many. However, these segmented worms only reach 1.5 millimeters in length. Their typical width is only 0.4 millimeters. No wonder they are easily overlooked.

Polydorella spionid worms
Polydorella spionid worms in action

However, on a dive at Sand Channels dive site, the surface of one sponge seemed to be quivering with dark hairs. According to the dive master who saw this activity, sponges of that type never displayed such frenetic motion. With the help of an excellent underwater photographer, a documentary photograph helped identify the tiny creatures that caused the pulsating appearance of the sponge’s surface. Upon seeing the photograph, Dr. Leslie Harris of Los Angeles County Natural History Museum confirmed those tiny worms were a species of Polydorella. That is one genus of spionid worms. The whips are their feeding palps. So, the motion that caught our attention was a great gathering of feasting Polydorella spionid worms.

Reproduction in Polydorella spionid worms

All members of the Polydorella genus undergoes asexual reproduction. The process is called paratomy. This type of worm has about fifteen segments, depending on the species. Basically, the worm grows additional segments. Upon reaching a certain length, a middle segment will develop into a head. Eventually, the new segments will separate from the parent segments. Scientists call the parental worm a stock and the new worm a stolon. Genetically, they are identical. The growth area on the parental stock follows segment ten or eleven. Moreover, a chain of up to five individuals can form prior to separation. 

Sexual reproduction is rare among Polydorella spionid worms. Only P. kamakamai and P. smurovi are documented as producing eggs. Indeed, eggs are rare. In research, only one of 290 Kamakama worms had eggs. That amounts to less than half of a percent. No eggs were found in the worms’ burrows. However, the Polydorella spionid worms photographed in Gorontalo contained multiple individuals bearing eggs. The egg sacs appear as white ovals in the picture. So, the documentation of so many eggs sacs makes this an extraordinary photo.

Life on a Sponge

A Striped triplefin ready to feed on spionid worms

These tiny worms live on various sponges. Sometimes, their mud tunnels can be observed on the surface of a sponge. Researches of Polydorella spionid worms in the Red Sea found sand grains in the intestines of the worms. For such a tiny creature, a sand grain is large to swallow. Scientists do not know why these worms would swallow sand grains, since they have no nutritional value. However, speculation is that worms help keep a sponge surface clean. In that way, the sponge enjoys benefit from hosting such tiny creatures.

In the photograph, the double whips coming from the worm’s head are used to gather food from the water or surface of the sponge. The motion of mass feeding caught the eye of our dive master in February 2019 when the photograph was taken.

Additionally, a couple of years later in June 2021, another of our dive masters photographed a Striped triplefin (Helcogramma striatum) eating Polydorella spionid worms. They were on an orange sponge.

These two photographs show how skilled Miguel’s Diving staff are in finding unusual critters in the ocean. For your chance to dive with our excellent dive masters, please make your dive reservations directly with Miguel’s Diving.  

Blacksaddle filefish mimics a toxic toby

Blacksaddle fishfish is a cute, tropical fish found occasionally throughout Gorontalo’s coral reefs. However, its saddle patterning closely resembles a toxic pufferfish.

Batesian Mimicry

A natural phenomenon where a harmless species mimics a harmful one is Batesian Mimicry. It gets its name from Henry Bates. He was a nineteen century English naturalist. He first detected this phenomenon among species of butterflies from the Amazon.

In Batesian mimicry, a mimic species will resemble a model species. In doing so, the mimic gains protection. So, predators mistake the harmless species for the harmful one.

Blacksaddle filefish and Blacksaddle toby

Blacksaddle filefish

, both species appear identical! However, divers can carefully observe distinctions. Most noticeable are the differing dorsal fins. The dorsal fin of a Blacksaddle filefish will be long, extending all the way to the tail base. However, the Blacksaddle toby has a tiny dorsal fin near the tail.

Naturally, filefish have a dorsal spine located behind the eyes that tobies lack. Sometimes, a filefish will flick its spine upwards. More often, the spine tucks unseen onto the fish’s head. Only male Blacksaddle tobies have beautiful blue lines streaming behind their eyes. However

, a male Blacksaddle filefish has four yellowish spines projecting from his tail base. These resemble a small brush.

Where to find Paraluteres prionurus

The Blacksaddle filefish live near the surface to a depth of 25 meters. Its maximum length is 11 centimeters. However

, most are about half that size or smaller. This fish is scattered throughout Indo-Pacific waters. It prefers clear lagoons and coral reefs that face the ocean. Although adults are usually in pairs, they often swim with Blacksaddle tobies. This behavior gives extra protection to the mimic filefish.
