Pink Skunk clownfishAmphiprion Perideraion
The Pink Skunk is the only species of anemonefish to primarily feed on algae.

The magnificent sea anemoneHeteractis Magnifica – has two feeding methods. The first one is through the photosynthesis of its symbiotic zooxanthellae, living in its tissues, the second by capturing its prey with its tentacles that allow it to immobilize its prey (small invertebrates, fry or juvenile fish) See also https://marinebiology.org/2019/01/19/clarks/

Etymology:
Amphiprion: Greek, amphi = on both sides + Greek, prion, -onos = saw

This Orangutan also lives in a Bubble

Orangutan Crab Achaeus japonicus
“orangutan” comes from the Malay words “orang” (man) and “(h)utan” (forest).  Hence, “man of the forest,” and these crabs really seem to look like their Terra-based namesakes. Not only do they resemble Orang-utans with their hair, but they also seem to sway their front legs from side to side in a very good imitation of an this great ape!!
It is frequently, but not always, found in association with the bubble coral Plerogyra sinuosa

Etymology:
japonicus – Latin, literally ‘Japanese’
The Achaeus Greek  – Ἀχαιοί, were one of the four major tribes into which the people of Classical Greece divided themselves (along with the Aeolians, Ionians and Dorians)

Crawling Rainbow

Glossodoris Cincta Nudibranch
Glossodoris Cincta Nudibranch

Glossodoris Cincta – Nudibranch
Feeds on sponges. When crawling, the gills make vibrating movements. When provoked, it discharges a white fluid from mantle dermal formations – in which they store distasteful chemicals from their food sponges to use defensively.

Etymology
Glosso= Greek ‘singular’ + dorís= ‘a nymph’, one of the daughters of Oceanus
cinctus= Greek ‘to put a belt around’

Scrambled Egg nudibranch

Sky Blue Phyllidia Nudibranch - Phyllidia varicosa -
Sky Blue Phyllidia Nudibranch – Phyllidia varicosa –

Sky Blue Phyllidia NudibranchPhyllidia varicosa
Probably the most frequently seen tropical Indo-Pacific nudibranchs. The phyllidiids are a group of firm, tough-bodied dorids in which the usual circlet of gills are replaced by leaf like secondary gills under the mantle skirt. It is sometimes called the “scrambled egg nudibranch.” These sea slugs are masters of chemical defense and contain a chemical mucus poisonous to fish and crustaceans. Scientists named it 9-isocyanopupukeane after the dive site, Pupukea, on O`ahu’s north shore. They are capable of killing all life in the aquarium if stressed in any way. They have no known predators.

Etymology
Phyllidium, from the Greek phyllos = ‘leaf’
verrucosa = from Greek ‘wart-like’

Where is Adam?

Ambon Crinoid Shrimp on Crinoid

Ambon Crinoid Shrimp – “Laomenes Amboinensis sp group”
Trying to identify which species of shrimp this is has proved to be more difficult then I desired. It has become a field of rabbit holes. Each time thinking that I found it it turn out No. I only have one photo of this fellow. To date, nine valid species are known in this genus and they show a wide diversity of morphological features such as shape of cornea and eyestalk, chelipeds and dactyli of ambulatory pereiopods, coloration and host specificity. Although many underwater photographs of these colorful shrimps are available in guide books, magazines and internet, there are rather few taxonomic reports on the species of this genus and most species only have limited confirmed geographical records. Moreover, it is highly likely that more species are present in Laomenes.

Etymology:
In Greek mythology Laomenes is a son of Heracles and Oreia, daughter of Thespius, king of Thespiae, and Megamede; during his hunt for the lion of Cithaeron to free Thespiae from this scourge, Herakles stayed with Thespius for 2 months, as a result all 50 daughters of Thespius and Megamede bore him a son each (except the oldest, who produced twin boys); Laomenes was one of these 51 boys.
 Ambon Island is part of the Maluku Islands of Indonesia +ensis, Latin denoting origin

This is the true color of the shrimp and the crinoid host. I have decided to name him “Skinny Adam L”.

It is a lighter shade red than Maroon 5.

Jon B, jason B said “for crinoid out loud that is a bad joke”.

tiny Warty Frogfish

Juvenile Warty Frogfish or Clown Frogfish - Antennarius maculatus
Warty Frogfish or Clown Frogfish – Antennarius maculatus

Juvenile Warty Frogfish or Clown FrogfishAntennarius maculatus
You can tell a Warty Frogfish from the painted frog fish by the skin being very warty (not so much as still juvenile) and a large triangle patch starting at the eye. The warty frogfish exhibits biofluorescence, that is, when illuminated by blue or ultraviolet light, it re-emits it as red, and appears differently than under white light illumination. Biofluorescence may assist intraspecific communication and camouflage.

Etymology
antenna – Latin =’ a sensory appendage on the head’ refering to the fish’s lure, + arius – Latin = ‘pertaining to’
maculatus – Latin = ‘spot, stain’

Shortpouch Pygmy Pipehorse and friends

Shortpouch pygmy pipehorse - Acentronura tentaculata
Shortpouch pygmy pipehorse – Acentronura tentaculata

Shortpouch pygmy pipehorseAcentronura tentaculata
Like a combination of seahorse and pipe fish: their tail is prehensile and used for anchorage, winding itself around pieces of algae or seagrass. However, the front part of the body is typical pipefish, with the head and body held in line rather than bent through and angle like seahorses. There is sexual dimorphism and the males are somewhat larger and more robustly built than the females. Because they are so small, the brood pouch is also large in proportion to the body, giving the males a somewhat more seahorse-like appearance than the females which have the typical slim linear form of pipefishes.

Skeleton Shrimp – Caprellidae family – amphipods. Females carry large number of transparent eggs inside the brood pouch (located on her abdomen) until they hatch.

Etymology:
Acentronura: Greek, a = ‘without’ + Greek, kentron = ‘sting’ + Greek, oura = ‘tail’

Pookey the pygmy pipehorse gathers his skeleton shrimp friends around to retell the great story of the day that Jon descended down from the waters above. Jon was dressed in a dark fake skin that was stretched very tight. Attached to each of his rear appendages were awkward rubber fins. His blue eyes were concealed behind a layer glass. A great hissing sound followed by a rumble of bubbles escaped from around Jon's mouth in a rhythmic pattern. Hssssss blublublublublublub Hsssssss blublublublublublub! He carried in front of him a great contraption that flashed a very bright light from the orbs at the end each of its antennas - one on each side of a single unblinking eye. Jon stayed only a few moments peering into this contraption and pointing that mysterious eye to and fro. FLASH Hssssss blublublublublublub…..FLASH Hssssss blublublublublublub. FLASH Hssssss blublublublublublub. Then, Jon swam off at a great speed. It was indeed a marvelous day.

Slender Filefish blends right in

Slender FilefishMonacanthus tuckeri
This filefish is a master of adaptive camouflage, it changes appearance in less than four seconds. Three-dimensional dermal flaps complement the melanophore skin patterns by enhancing the complexity of the fish’s physical skin texture to disguise its actual body shape. Found over sandy and rocky bottoms. Usually they live solitary or in pairs between gorgonians, sponges or near coral growths. Often they stay vertically in the water. Especially between gorgonians they are difficult to spot in this position. Feeds on algae and invertebrates. Due to the extremely small size of the slender filefish, they do not lie on the seabed as bigger fish do, but use their mouth to grasp the soft corals which prevents them from drifting with the sea currents.

Etymology:
Monacanthus: Greek, monos = ‘one’ + Greek, akantha = ‘thorn’

Painted frogfish

Painted Frogfish - Antennarius pictus
Painted Frogfish – Antennarius pictus

Painted FrogfishAntennarius pictus – Has a lure which is about twice as long as the second dorsal spine. Nearly always 3 light-edged spots on tail fin. A. pictus shows a lot of different colors and changes them quite often.

I was disappointed that I could not capture a photo of the little lure waving about. When I put my camera in the housing I did not get the strobe hot shoe clicked completely in place. This was lighted by holding my dive light from above and I couldn’t produce enough light for a fast enough shutter speed to catch the waving.

Etymology
Antennarius: From Latin, antenna, antemna = ‘sensory organ’
pictus: From Latin = ‘painted’


It’s a tentacular spectacular!

Phyllodesmium briareum - Nudibranch
Phyllodesmium briareum – Nudibranch

Phyllodesmium briareum – Nudibranch – There is a lot going on in those wavy arms. The name briareus was apparently given to it because it uses camouflage and looks like the soft coral Briareum violacea with which it is often found. Their specific name briareum comes from Briareos, one of three Greek storm giants who each had one hundred hands and fifty heads. P. briareum spends the day feeding on various kinds of soft coral, but they also have contains zooxanthellae which live in specialized ducts in the digestive gland. They do their photosynthesis thing and provide sugars.

The tentacles are cerata (from the Greek word meaning “horn”, a reference to the shape of these structures) of conventional aeolid shape. Aeolids (a suborder of Nudibranchia)take their name from the Greek god of the winds, Aeolus because of the waving of their cerata resembles streamers in the wind.
All aeolids have these dorsal and lateral outgrowths of the body. They are a blood-filled tube which contains a duct of the digestive gland. At the tip of the ceras in most aeolids is a sac, called the cnidosac which stores stinging nematocysts from the cnidarians (sea anemones, hydroids etc) on which they feed. Aeolids can discharge these nematocysts in their own defense. Some aeolids, such as species of Phyllodesmium which feed on soft-corals, do not have a cnidosac because the nematocysts of soft-corals are of little use in defense. Instead their cerata produce a horrible sticky secretion at the tip of the ceras. The cerata can even drop off and wriggle around, hopefully distracting assailants giving it a chance to escape.

Being an aeolid, P. briareum lacks the gills found in many other nudibranches. Instead, they do all their breathing straight through the skin, but particularly through those wonderful tentacles which are known as cerata.
