Cuttlefishes and octopuses. Part 16 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 In this video I look at cuttlefishes (Sepiida) and octopuses (Octopoda); types of cephalopod (Cephalopoda) found in the Lembeh Strait. The broadclub cuttlefish (Sepia latimanus) is the second largest species of cuttlefish, and the most common on coral reefs. It can adopt an infinite number of textures, colours and poses to camouflage itself, communicate and to hypnotize prey. As the name suggests, the crinoid cuttlefish (Sepia sp.) tends to hang around feather stars. We find one hiding amongst the branches of a decaying staghorn coral. This is an undescribed species known only from Indonesia, and recognised by the dark spots at the front of its lower arms. The dwarf cuttlefish, or stumpy-spined cuttlefish (Sepia bandensis) is a tiny species that is usually only seen at night. Rather than swimming, it usually uses its lower arms to walk on and explore the seabed. It is often found in association with echinoderms such as sea urchins. Another species that walks on its arms is one of the real stars of Lembeh, the flamboyant cuttlefish (Metasepia pfefferi). When disturbed it abandons its camouflage and the skin adopts spectacular shades of purple and yellow, with waves of white radiating down the mantle. The colour changes are achieved by adjusting millions of pigmented cells in the skin called chromatophores. This is an example of aposematic coloration whereby a creature warns potential predators of its toxicity. Scientists have recently discovered that the flamboyant cuttlefish's muscle tissue contains a unique and highly potent toxin, proving that this display is no bluff. We see an adult flamboyant cuttlefish using its special feeding tentacles to snatch prey such as small shrimps and gobes, and a tiny juvenile raising its median tentacles, a common threat display amongst cuttlefishes. Cuttlefishes' intelligence and unique powers compensate for their lack of a protective shell. They have the highest brain-to-body-mass ratio of all invertebrates, and researchers have shown them to possess a good memory and a high capacity for learning. Octopuses are closely related to cuttlefishes and have similar characteristics and intelligence. At TK we encounter an undescribed octopus, a near relative of the mimic octopus and wonderpus, retreating to its burrow with a captured crab. The octopus usually injects the crab with a paralysing saliva before using it's parrot-like beak at the centre its arms to excavate the meat from the crab. Finally on a night dive at Aer Perang we encounter a starry night octopus, Callistoctopus luteus, twisting and turning around the reef as it tries to escape my attention. 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..

Molluscs (mollusks, Mollusca) including cowries, sea slugs (in particular, nudibranchs) and giant clams. Part 14 of my DVD, "Reef Life of the Andaman", available at http://www.bubblevision.com/marine-life-DVD.htm The first category of molluscs we look at is cowries in the family Cypraeidae, which is in the class gastropods (Gastropoda). Cowries have a pretty, glossy shell which can be covered by their bilobed mantle. The mole cowry (Talparia talpa) and tiger cowrie (Cypraea tigris) are two common species that feature from the Mergui Archipelago in Burma (Myanmar). We then take a look at some of the sea slugs (opisthobranchs, Opisthobranchia) to be found in the Andaman Sea. The area has many pretty nudibranchs (Nudibranchia) and amongst others we find a Chromodoris geminus at Richelieu Rock, north of the Similan Islands in Thailand, and a group of 3 Chromodoris annulata at Black Rock in the Mergui Archipelago. Wart slugs in the family Phyllidiidae are also represented, particularly those of the Phyllidia genus such as Phyllidia varicosa. Finally we take a look at the fluted giant clam, Trdacna squamosa, which is a large bivalve (bivalvia) found on many Thailand dive sites. 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 molluscs in English, German or Dutch, along with dive site names. Thanks to Mark Ellison for the first music track, "Hidden Depths", and to Kevin MacCleod (http://www.incompetch.com) for the second music track, "Deliberate Thought". "Reef Life of the Andaman" is being serialised weekly on YouTube. Please subscribe to my channel to receive notifications of new episodes as I release them. The series features descriptions of 213 different marine species including more than 100 tropical fish, along with sharks, rays, moray eels, crabs, lobsters, shrimps, sea slugs, cuttlefish, squid, octopus, turtles, sea snakes, starfish, sea cucumbers, corals, worms etc.. I have more scuba diving videos and underwater footage on my website at: http://www.bubblevision.com I post updates about my videos, and interesting underwater videos from other filmmakers here: http://www.facebook.com/bubblevision http://www.twitter.com/nicholashope The video was shot by Nick Hope with a Sony VX2000 DV camera in a Gates housing. It was edited in Sony Vegas Pro then deinterlaced with QTGMC and upscaled to 720p HD in AviSynth.
