  • A harlequin shrimp (Hymenocera picts) in its coral home in the Lembeh Straits, Indonesia. They are found at coral reefs in the tropical Indian and Pacific oceans and can reach about 5 centimetres  in length, live in pairs and feed exclusively on starfish, including crown-of-thorns (Acanthaster) starfish. It does seem to prefer smaller, more sedentary starfish, but as these generally are not sufficiently numerous for its needs, it commonly will attack Acanthaster, both reducing its consumption of coral while under attack, and killing it within a few days.<br />

  • A crocodile flathead (Cymbacephalus beauforti) keeps an eye on its surroundings. Their large eyes are explained by the fact that they are mostly nocturnal. Lembeh Straits, Indonesia.

Nudibranchs or sea slugs come in an amazing variety of colors and shapes making their terrestrial namesakes seem very drab.

  • 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.

  • 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.

  • Far from the idyllic "Nemo" life in a host anemon, within a group of clownfish, there is a strict hierarchy of dominance. The largest and most aggressive female is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. The clownfish are hermaphrodites, meaning that they develop into males first, and when they mature, they become females. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males would become a female. The rest of the remaining males will move up a rank on the hierarchy.

  • 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.

  • 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.

  • 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.

  • Two Phyllidia marindica nudibranchs prepare to mate. These animals are widespread throughout the Indian and Pacific Oceans.

  • 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.

  • 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.

  • 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.
