  • Bornella anguilla nudibranch, feeding on hydroids.  Mergui Archipelago, Myanmar, Andaman Sea

  • This rare photo shows a Muddy Argonaut, a.k.a. Paper Nautilus, Argonauta hians, grasping a jellyfish while feeding on a Comb Jelly. The Argonaut apparently uses the jellyfish to shield itself from predators. Argonauts are not true nautiluses, but rather a family of open-ocean octopuses.  Only the females produce the delicately beautiful shell, which is actually an egg case.  Mergui Archipelago, Myanmar, Andaman Sea, Indian Ocean

    2009MARCH12sail112.tif
  • A Golden Wentletrap Snail, Epitonium billeeanum, has inserted its proboscis into its favorite prey, a colony of Orange Cup Coral, Tubastraea sp. Soon after consuming each coral polyp, the snail deposits sticky, yellowish eggs in the empty coral skeleton.  The eggs bear a close resemblence to the stinging tentacles of the coral, an adaptation probably designed to discourage predators from eating the eggs.  Richelieu Rock, Thailand, Andaman Sea

  • A tiny Tiger Ovulid, Cuspivolva tigris, makes its way through a forest of gorgonian coral polyps, which are open and feeding in the current. The Ovulid, which belongs to a group of sea snails known as Allied Cowries, lives and feeds upon gorgonians of the genus Euplexaura. The striking coloration is only a thin, fleshy mantle; the actual shell is rather drab. Richelieu Rock, Thailand, Andaman Sea
    cowrie17LM.tif
  • Say Ahh! A rare, brilliant yellow Weedy Scorpionfish, Rhinopias frondosa, flexes its jaws, as if bored. The actual reason for this behavior is probably to send a threatening message to the photographer, who has no doubt worn out his welcome. Scorpionfish also stretch their jaws regularly to stay limber for feeding opportunities. Manado, North Sulawesi, Indonesia, Pacific Ocean

  • Humpback Whales, Megaptera novaeangliae. In this case a mother and calf surface to breathe, accompanied by an adult male escort.

  • These delicate looking nudibranchs, Tenellia sibogae, are mating, surrounded by the stinging hydroids on which they feed. Once ingested, the hydroids' stinging cells are actually kept as live captives by the nudibranchs, transferred to the tips of their colorful cerrata for their own self-defense! Richelieu Rock, Thailand, Andaman Sea

  • Rarely seen by divers, a pod of False Killer Whales, Pseudorca crassidens, swims in tight formation.

  • A Giant Manta, Manta birostris, feeds on plankton while cruising just below the surface. The long flaps on either side of its mouth, known as cepahlic lobes, help to funnel water into its mouth so the plankton can be strained out. Narcondam Island, Andaman Islands, India, Andaman Sea

  • A Blue-spotted Coral Grouper, Cephalopholis miniata, says Ahhh while a Skunk cleaner shrimp, Lysmata amboinensis, inspects it for parasites. In a perfect example of symbiosis, the shrimp feeds on the parasites it removes, thus benefitting both parties.  Supremely confident in its status as a valued partner, the shrimp grooms its customers from head to tail, sometimes even crawling inside the mouth. Similan Islands Marine National Park, Thailand, Andaman Sea
