Cardinalfishes & trumpetfish. Part 6 of my documentary, "Mucky Secrets", about the fascinating marine creatures of the Lembeh Strait in Indonesia.

In this video I first take a look at the Banggai cardinalfish, Pterapogon kauderni. This is an invasive species which was introduced to the Lembeh Strait in the year 2000, and now competes with anemonefish for territory. Although it appears to be thriving in the Lembeh Strait and a few other locations, the Banggai cardinalfish is nonetheless still an endangered species because of its popularity in the ornamental fish trade.

We then encounter other species of cardinalfish (Apogonidae) in the area, Moluccan cardinalfish, Ostorhinchus moluccensis, the orbiculate cardinalfish, Sphaeramia orbicularis, and the frostfin cardinalfish, Ostorhinchus hoevenii, sheltering in the spines of sea urchins.

Finally we witness a trumpetfish, Aulostomus chinensis, preying on a small group of frostfin cardinalfish. The trumpetfish's slim profile and stealth allow it to creep up very slowly on the unsuspecting cardinalfish, before making its attack. The trumpetfish sucks in the cardinalfish in a method known as "pipette feeding".

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.

"Mucky Secrets" is being serialised weekly on YouTube. Please subscribe to my channel to receive notifications of new episodes as I release them. The series will feature a huge diversity of weird and wonderful marine animals including frogfish, nudibranchs, scorpionfish, crabs, shrimps, moray eels, seahorses, octopus, cuttlefish etc..

Crabs & Shrimps at Night. Part 27 of my DVD, "Reef Life of the Andaman", available at http://www.bubblevision.com/marine-life-DVD.htm

Night diving offers the opportunity to see many crustaceans that are typically hidden in the reef during daylight, but are highly active under the hours of darkness. This video features 13 species.

At Koh Doc Mai, near Phuket in Thailand, and in the Similan Islands, we see banded coral shrimps (Stenopus hispidus) plucking plankton from the water to eat. Rock cleaner shrimp (Urocaridella sp.) are busy cleaning a large snapper and a fimbriated moray eel (Gymnothorax fimbriatus).

Space is at a premium on the reef. In the Mergui Archipelago in Burma (Myanmar) we see a fimbriated moray sharing its home with a variable coral crab (Carpilius convexus).

Female crabs carry their eggs under their apron for a few months while the embryos develop. We witness the dramatic sight of a spendid round crab (Etisus splendidus) releasing her brood. As she pumps her lower body, thousands of tiny larvae are released and drift away in the current.

At Thailand's Boonsung wreck, a crucifix crab (Charybdis (Charybdis) feriata) tries to appear as large and intimidating as possible by spreading its claws, before escaping into the shelter of the wreck, while at Western Rocky Island we see a tiny bull crab (Naxioides taurus) crawling across a gorgonian sea fan.

The flat rock crab, Percnon planissimum, is a common sight in the Andaman Sea, as is the swimming crab, Charybdis sp., which we see defending its territory by fighting off a passing common decorator crab (Schizophrys aspera). This decorator crab has large claws and covers itself with other marine organisms such as stinging hydroids for camouflage and defence. The horrid elbow crab (Daldorfia horrida) becomes completely encrusted with growth, while the spider decorator crab (Camposcia retusa) covers itself with sponges which continue to grow while on the crab, and enable it to blend in with the reef. The sponge crab, Dromia dormia, carries a large spone with its rearmost legs. We see one fling itself off the edge of the reef in an attempt to escape our lights.

Hermit crabs live inside empty snail shells in order to protect their soft abdomen. We see white-spotted hermit crabs (Dardanus megistos) in a variety of different shells. Anemone hermit crabs (Dardanus pedunculatus) carry live sea anemones on its shell as an extra defence. At Honeymoon Bay we a pair of them, perhaps in a dispute over territory.

The full narration is available as English, German or Spanish subtitles by turning on the closed captions (CC). There are also closed captions available showing scientific and common names of the marine life in English, German or Dutch, along with dive site names.
