The demon stinger and waspfishes. Part 15 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia. Watch the full 90-minute documentary at http://www.youtube.com/watch?v=nJMZ6reOB0E

One fish that divers should be wary of in the Lembeh Strait is the demon stinger (Inimicus didactylus) as its sting is extremely painful and can be deadly to humans. They have excellent camouflage and often lie partially buried in the muck. These fish are more closely related to the lethal stonefish than to scorpionfishes, and are known by a multitude of other evocative common names including spiny devilfish, bearded ghoul and sea goblin.

The lower two rays of the pectoral fins are detached from the fin, and the demon stinger walks on them in a manner similar to some dragonets.

Demon stingers have no known predators. Many fellow bottom dwellers are oblivious to their existence. We see a fireworm (Chloeia parva) a type of bristleworm, crawling right over the top of a well-camouflaged demon stinger.

Like their scorpionfish relatives, waspfishes (family Tetrarogidae) are also armed with venomous spines in their dorsal fin. We see another type of polychaete worm wriggling past a wispy waspfish (Paracentropogon longispinis). The wispy waspfish's coloration is variable.

Bandtail waspfishes (Paracentropogon zonatus) are sometimes found too, and the whiteface waspfish (Richardsonichthys leucogaster) is one of the more common types.

With its spines erect, like its namesake's crest, the cockatoo waspfish (Ablabys taenianotus) sways from side to side, mimicking a dead leaf in surge. They are sometimes found in pairs on the open seabed.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.

The full Mucky Secrets nature documentary features a huge diversity of weird and wonderful marine animals including frogfish, nudibranchs, scorpionfish, crabs, shrimps, moray eels, seahorses, octopus, cuttlefish etc..

Mandarinfish & other dragonets. Part 9 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video I study dragonets including the amazing mandarinfish. Dragonets are benthic animals, meaning that they live on the seabed. They thrive in the muck of Lembeh. Dragonets are well-adapted to benthic life. They are well camouflaged and at night they bury their bodies. The eyes and gills are placed high so only they remain above the sand.

The fingered dragonet, Dactylopus dactylopus, is found in the Lembeh Strait. The first ray of each pelvic fin is effectively a limb or "finger" that the dragonet uses to walk along the seabed and dig for food. The male has warpaint-like facial markings and has long filamented rays on its dorsal fin that it holds forward when walking. The female has a bright orange upper lip.

The orange-black dragonet, Dactylopus kuiteri, is very similar. We encounter an adult and juvenile in close proximity, feeding on the seabed.

The Morrison's dragonet, Synchiropus morrisoni, shuffles around the seabed without the aid of the separated fin rays.

A similar species of dragonet, the mandarinfish, Synchiropus splendidus, stays well hidden amongst shallow hard corals during the day. At dusk the males eagerly seek out female mates. During the hunt they hold their first dorsal fin aloft as an advertisement to the females and a warning to competing males.

When a mate has been found, the female rests on the larger male's pectoral fin and the couple rise up together from the reef. At the peak of their ascent they simultaneously release sperm and eggs and then make a dash for cover as the spawn drifts away in the current.

This frenzy of sexual activity typically lasts some thirty minutes until nightfall. If fertilized, the eggs will hatch about a day later and the tiny larvae will drift for a further week or two before settling onto the bottom to begin their benthic life.

There are English captions showing either the full narration or the common and scientific names of the marine life, along with the dive site names.
