  • Super macro study of the head of a crested nembrotha (Nembrotha cristata) nudibranch. These sea slugs come in an amazing variety of shapes, sizes and colors.

  • Close up of a nudibranch's rhinophore. These animals use these organs to detect chemicals in the water to effcetively find food and potential mates. They also sense water movements, giving the nudibranch information about its environment.

  • A striated or "hairy" frogfish (Antennarius striatus) waves its esca or lure in an attempt to attract prey. Some think that the fish's "hairs", which are actually dermal spinules,  are designed to make them look like urchins. My experience is that they are not always found among urchins, so the "hairs" are simply a good way of breaking up the fish's outline for camouflage.

  • A clown frogfish  (Antennarius maculatus) makes its ponderous way across the sea bed. Frogfish move using their modified pectoral and pelvic fins to walk along the floor as this one is, not unlike a biped's walking gait  or they can make short "hops"  In the case of the latter, they move their pectoral fins simultaneously forward and back, transferring their weight to the pelvic fins while moving the pectorals forward.

  • A Nembrotha purpureolineata feeds as it moves across the seabed. In common with many sea slugs, they are specialised eaters, only feeding on tunicates or sea squirts.
    160927-ahanlon-504869.jpg
  • Close up stady of the rhinophores of a Marie's Mexichromis nudibranch. (Mexichromis mariei). These sensory organs provide a great deal of information about chemical and scents in the water as well as currents and water movements. Taken in the Lembeh Straits, Sulawesi, Indonesia.
    160927-ahanlon-504981.jpg
  • Risbecia tryoni nudibranchs apparently nuzzle priot to mating. It is likely that they are actually using the chemical receptors on their rhinophores to sense the readiness of the other.
    160930-ahanlon-24432.jpg
  • Two Phyllidia marindica nudibranchs prepare to mate. These animals are widespread throughout the Indian and Pacific Oceans.
    161005-ahanlon-508442.jpg
  • A bus stop nudibranch (Goniobranchus hintuanensis) lifts its mantle or skirt as it negotiates the sea floor. These species were re classified with the help of DNA analyisis in 2012. Nudibrachs move with the help of a muscular foot, that has rythmic contractions along its length.
    161005-ahanlon-508611.jpg
  • The colors of this Flabellina rubrolineata warn other animals that it may give them a anasty surpise if they try to eat it. It can store the poison from the stinging cells of the animals it eats, and use it as aweapon in its defence.

  • Geometric Chromodoris (Chromodoris geometries) moving across its substrate of a piece of fallen timber. In common with many nudibranchs, this Chromodoris feeds on hydroids, coral, sponges and anemones. As it moves, its mantle "waves" up and down.

  • The red on this Nembrotha kubaryana signal danger to any passing animla that thinks that it might be a good meal!

  • A redline flabellina (Flabellina rubrolineata) strikes a pose. Taken in the Lembeh Straits, Sulawesi, Indonesia.
    160928-ahanlon-505409.jpg
  • This Marie's Mexichromis (Mexichromis mariei) is laying a trail or ribbon of eggs. Each species of nudibranch has a distinct pattern when it lays eggs and this allows biologists to identify which eggs belong to which animal.
    161003-ahanlon-507096.jpg
  • It is obvious how the construction of this crested nembrotha"s (Nembrotha cristata) rhinophores have been designed in order to maximise their surface area. Like the cooling fins on a motornike engine, this increased surface area allows them to sample more water around them and hence obtian a better picture of their environment.

  • A Nembrotha kubaryana nudibranch makes its way across an encrusting sponge. Taken in the Lembeh Straits, Sulawesi, Indonesia.
    161012-ahanlon-501639.jpg
  • Nudibranchs will often climb up bits of coral in order to use their extraordinary chemo receptor rhinophores to "taste" the water and sense food sources and threats.
    161005-ahanlon-508450.jpg
  • A rusty parrotfish (Scarus ferrugineus) displays its amazing mouth parts. These form the major component that parrotfishes use for their duties as the constant gardeners of the reef. They play a crucial role in keeping it healthy, suppressing weed, removing sediment and helping the corals to regrow after a setback.

  • A sterlet (Acipenser ruthenus) observes te photographer closely. These amazing animals are essentially evolutionary survivors and have lived litle changed for many thousands of years.

  • A girdled Glossodoris (Glossodoris cincta) nudibranch makes its way across the sea bed. Nudinbranchs use muscular contractions of their mantles to undulate and allow them to move.
    160928-ahanlon-505450.jpg
  • Although it looks like a fire breathing dragon, a tiny Gabriela's tambja (Tambja gabrielae) uses its rhinophores to evaluate its environment.
    160929-ahanlon-505963.jpg
  • This Marie's Mexichromis (Mexichromis mariei) is laying a trail or ribbon of eggs. Each species of nudibranch has a distinct pattern when it lays eggs and this allows biologists to identify which eggs belong to which animal.

  • A Yamasu's cuthona (Cuthona yamasui) makes its way across the sea bed
    161013-ahanlon-501724.jpg
  • There are still many species of nudibranch that are as yet undescribed by science. This animla rejoices in the name Nembrotha species 2 and is not yet properly taxonomically classified. The use of genetic sequencing has also created many new controversies, with many existing families and species being reclassified. This partcular specimen has tangled with something that has removed one rhinophore.

  • A beautifully colored Dermatobranchus ornatus nudibranch moves across the corals of a reef in Indonesia.
    160915-ahanlon-66.jpg
  • This is the brachial plume, or the gills of this nudibranch. As it lives underwater, it does not breathe in the same way that mammals do, but this organ allows it to extract oxygen from the water.
    160928-ahanlon-505622.jpg
  • Magnificent vibrant colors serve as a warning that this Hypselodoris apolegma nudibranch is likely to be an unpleasant meal for any would be predator.

  • Like a ship plowing its way across the ocean's surface, this many lobed ceratosoma (Ceratosoma tenue) moves across the sea bed.
    161001-ahanlon-506211.jpg
  • Nudibranch means "naked gills". These animals have external organs that allow them to extratct oxygen from the water. This close up shows the brachial plume, or its lungs.
    161001-ahanlon-506332.jpg
  • The vibrant colors of this Hypselodoris apolegma, attempt to warn other animals that it may not be so good to eat.
    161011-ahanlon-500775.jpg
  • A streaked Chromodoris (Chromodoris strigata) turns away from the camera. The rhinophores allow the animal to make sense of its environment and are complex sesnory organs. Taken in the Lembeh Straits, Sulawesi, Indonesia.
    161013-ahanlon-501902.jpg
  • Not all nudibranchs are brightly colored! This Rudman's phyllodesmium (Phyllodesmium rudmani ) has evolved to look like the polyps of the Xenia soft corals that it normally inhabits.

  • A super macro image of a peacock tail anemone shrimp (Periclimenes brevicarpalis) on its anemone Cryptodendrum adhaesivum.

  • A super macro image of the mouth parts of a coleman shrimp ( Periclimenes colemani) in its fire urchin (Asthenosoma varium) home.<br />
Coleman shrimps are only found on fire urchins and live in an obligate symbiosis with their host. They feed on the soft tube feet and tentacles of the sea urchin, which does not seem to be severely harmed. The venomous spines of the urchin provide an excellent defense from any would be predators too.
