  • Rarely seen by divers, this adult female Ribbon Eel, Rhinomuraena quaesita, is distinguished by its yellow coloration. Juveniles are mostly black, changing into  predominantly blue males, eventually turning into yellow females at about 85 cm length. This image is doubly rare because the animal is in the open; normally only head and shoulders protrude from burrow. Lembeh Strait, North Sulawesi, Indonesia, Pacific Ocean

  • Rarely seen by divers, this female Muddy Argonaut, a.k.a. Paper Nautilus, Argonuta hians, appears ready to abandon her egg-laden shell. This specimen had apparently been attacked and injured by a predator, which may have prompted the evacuation. While superficially resembling a nautilus, Argonauts are actually a type of pelagic octopus. Only females produce a shell, which also serves as an egg case. Males are much smaller, and seen even less often than females. Mergui Archipelago, Burma, Andaman Sea, Indian Ocean

  • Occasionally found in large numbers on beaches, and in this case underwater, these  shells are actually egg cases, made by female Paper Nautilus, Argonauta hians. The tiny male Argonauts have no shell and die soon after mating, while females live in these delicate shells, which also serve as egg cases until  their brood hatches, after which the females die and the shells are abandoned.  Similan Islands, Thailand, Andaman Sea, Indian Ocean

  • A female Pharaoh Cuttlefish, Sepia pharaonis, hovers near a rocky reef while 2 males compete for her attention. The dominant male maintains close contact with the female to deny competing males an opportunity to mate with her. During such courtship rivalries, males display spectacular, rapidly changing color patterns, probably meant to intimidate their rivals. Richelieu Rock, Thailand, Andaman Sea, Indian Ocean

  • A pair of Pharaoh cuttlefish, Sepia pharaonis, copulating. Within minutes of seperating, the female will begin depositing eggs, one at a time, in rocky crevices. During this process the male will maintain close contact witht the female in hopes of preventing competing males from mating with her. Richelieu Rock, Thailand, Andaman Sea, Indian Ocean

  • This pair of Indian Flame Basslets, Pseudanthias ignitus, are courting in mid-water, as they often do at dusk.  The female, above, pales in comparison to the vividly colored male, which displays its most brilliant coloration during such mating rituals.  The pair mated moments after this photo was taken, releasing eggs and sperm into the water column, to be taken wherever the current carried them.

    Cuttlefish Romance 16x20
  • Reminiscent of a dragon emerging from its lair, a male Ribbon Eel, Rhinomuraena quaesita, peers from a crevice. This species is a protandrous hermaphrodite, meaning that males change into females. Juveniles are black with yellow trim, adult males are neon blue w/ yellow; females, which are uncommon, are entirely yellow.  Lembeh Straight, N. Sulawesi, Indonesia, Pacific Ocean

  • Muddy Argonaut, a.k.a. Paper Nautilus, Argonauta hians, grasping a jellyfish. Like the small butterfish, the Argonaut uses the jelly to shield it from predators. Argonauts are not true nautiluses, but rather a group 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
