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)

Clownfish and its Tent

Clark’s AnemonefishAmphiprion Clarkii
In a group of clownfish, there is a strict dominance hierarchy. The largest and most aggressive fish is female and is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature, they become females. They are not aggressive.

Magnificent Sea AnemoneHeteractis Magnifica
Venom present in sea anemone (Heteractis magnifica) induces apoptosis in non-small-cell lung cancer A549 cells through activation of mitochondria-mediated pathway. The longevity of in the wild is unknown, but estimated that some of these anemones are hundreds of years old. The Clarks Anemonefish lifespan is only 14 years. The reproduction of the anemone can be sexual by simultaneous transmission of male and female gametes in the water or asexual by scissiparity,which means that the anemone divides itself into two individuals, separating from the foot or the mouth. That makes me say “Hmmm, very impresive.

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 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 – “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”.

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.

A Sea Cookie Monster?

Spotted Worm Sea Cucumber - Synapta maculata
Spotted Worm Sea Cucumber – Synapta maculata

Spotted Worm Sea CucumberSynapta maculata – Sometimes growing as long as 10 ft, it is one of the longest sea cucumbers in the world. The 15 tentacles of Synapta maculata surround the mouth and are used in surface feeding. They are about 1 in long when extended and have a short stem and a feather-like blade with thirty to forty pairs of pinnules (secondary branches). The outer surfaces of the tentacles have numerous bulges and are adhesive while the inner surfaces are smooth, with clusters of cilia on the proximal parts. The tentacles are in continuous motion; they flatten themselves against the substrate or seagrass leaf blades and collect food particles by adhesion, then bend inwards until the tips are in the mouth, where the food is scraped off by the buccal (mouth) sphincter muscle. The whole process takes only a few seconds, and several tentacles can deliver their loads at the same time. You can watch them go at https://www.youtube.com/watch?v=7ru1fcsFp1M

Synapta: Latin ‘joined together’
maculata: Latin maculosus ‘spotted’
