  • Soft corals festoon the shallow part of the reef. As most corals can produce the bulk of their own food by photosynthesis, they can survive in areas that have little or no nutrients in the water. It also means that they need sunlight and hence clear water. Ths makes them an ideal underwater photography subject!

  • 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.

  • 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.

  • The red on this Nembrotha kubaryana signal danger to any passing animla that thinks that it might be a good meal!
    160928-ahanlon-505298.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
  • 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.

  • 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.
    161005-ahanlon-508817.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 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.

  • 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.
    160927-ahanlon-504854.jpg
  • 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
  • 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
  • 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.
    161005-ahanlon-508791.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.

  • 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
  • A Yamasu's cuthona (Cuthona yamasui) makes its way across the sea bed
    161013-ahanlon-501724.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
  • 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
  • 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
  • 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
  • Magnificent vibrant colors serve as a warning that this Hypselodoris apolegma nudibranch is likely to be an unpleasant meal for any would be predator.
    160928-ahanlon-505619.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.

  • Portrait and detail of the "hairs" of a striated frogfish (Antennarius striatus). Lembeh Straits, North Sulawesi, Indonesia.
    Bad hair day
  • These  Clarks Anemonefish (Amphiprion clarkii), in common with many reef fish, show that you are too close by "yawning" at you. Komodo, Indonesia.
    Underwater colors
  • Colorful soft corals festoon ever available spaces in the shallow sunlit area on top of the reef. Komodo, Indonesia.

  • A geometric chromodoris (Chromodoirs geometrie) poses on a piece on bamboo on the house reef at Lembeh Resort, Sulawesi, Indonesia.<br />
<br />
Nudibranchs or sea slugs come in an amazing variety of colors and shapes making their terrestrial namesakes seem very drab.
    Striking a pose
  • A Goniobranchus aureopurpurea nudibranch lifts its "skirts" or mantle as it moves across the bottom. The animal's rhinophores are able to sense chemicals and currents within the water around it.
    140213-ahanlon-86249.jpg
  • This nudibranch has evolved to be able to generate its own food by having photosynthetic zooxanthellae algae within it. The solar-powered phyllodesmium (Phyllodesmium longicirrum) ingest green algae without completely digesting it and stores the algae's chloroplasts in the obvious spots on its body.
    140209-ahanlon-84367.jpg
  • 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.
    131022-ahanlon-82115.jpg
  • 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.
    140211-ahanlon-85444.jpg
  • Nudibranchs lay chacteristic patterns of eggs on rocks or the sea bed. This many lobed ceratosoma (Ceratosoma tenue) is layinga spiral of red eggs on a small rock
    131022-ahanlon-82070.jpg
  • This nudibranch has evolved to be able to generate its own food by having photosynthetic zooxanthellae algae within it. The solar-powered phyllodesmium (Phyllodesmium longicirrum) ingest green algae without completely digesting it and stores the algae's chloroplasts in the obvious spots on its body.
    140209-ahanlon-84370.jpg
  • Two crested nembrotha (Nembrotha cristata) nudibranchs doing their bit for survival of the species. Nudibranchs are typically both male and female, and meet up to breed with each other simultaneously.

  • A sunburst over a spectacular reef underlines how important the sun is to all life on earth. Komodo, Inonesia
    140207_Komodo_wainilu_83776.jpg
  • Emperor shrimp (Periclimenes imperator) catching a ride on a many lobed ceratasoma nudibranch (Ceratosoma tenue). These shrimps seem to live in a commensal relationship with larger nudibranchs or sea slugs, picking up detritus from the sea floor as their hosts move along it.
    Hitching a ride
  • A coconut octopus (Amphioctopus marginatus) peers out of its shell home.

  • Sarcophyton soft corals festoon the shallow part of the reef. As most corals can produce the bulk of their own food by photosynthesis, they can survive in areas that have little or no nutrients in the water. It also means that they need sunlight and hence clear water. Ths makes them an ideal underwater photography subject!
    140207-ahanlon-839274912 x 7360.jpg
  • Greater blue ringed octopus (Hapalochlaena lunulata) flashes blue rings when it feels threatened. These tiny animals (about the size of a golf ball) pack a potentially life threatening venom.
    Day 2-88623.jpg
  • Spotted porcelain crab (Neopetrolisthes maculatus) on its host anemone. It is adopting a defensive position, warding me off....
    What you looking at?
  • Coleman shrimps (Periclimenes colemani) in their fire urchin (Asthenosoma varium) home.<br />
<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.
