Orange cup coral - Tubastraea Coccinea
Orange cup coral – Tubastraea Coccinea

Orange cup coral – Tubastraea Coccinea –
belongs to a group of corals known as large-polyp stony corals. This non-reef building coral extends beautiful translucent tentacles at night. Tubastraea coccinea is heterotrophic and does not contain zooxanthellae in its tissues as many tropical corals do, allowing it to grow in complete darkness as long as it can capture enough food, namely plankton.

It is nice to see Tabastrea Coccinea in its natural environment. OCC has been introduced to all continents except Antarctica and is thought to compete with native benthic invertebrates for space and to compromise their communities. The reduction of native sponges and native corals could also have significant flow-on effects for entire ecosystems. OCC was introduced in the Caribbean in the late 1930’s or early 1940’s at Curaçao and/or Puerto Rico probably transported by fouled vessels, oil and gas platforms, artificial reef structures, or ballast waters.

Etymology
Tubus = tube; +astrea = Astrea – Astraea, daughter of Zeus and Themis, a goddess of justice named after the stars.
coccineus = Latin meaning ‘red like a berry’, scarlet.

Yellow-lipped sea krait
Yellow-lipped sea krait
– Laticauda colubrina

Yellow-lipped Sea Krait or Banded Sea Krait – Laticauda colubrina
The worlds most venomous sea snake, found in tropical Indo-Pacific oceanic waters. They have distinctive black stripes and a yellow snout, with a paddle-like tail for use in swimming.

It spends much of its time underwater in order for it to hunt, but returns to land to digest, rest, and reproduce. It has very potent neurotoxic venom which it uses to prey or when feeling threatened by attack. When hunting, banded sea kraits frequently head into deep water far from land. Individual banded sea kraits return to their specific home islands, exhibiting philopatry.

Hunting is often performed alone, but may also do so in large numbers in the company of giant trevally and goatfish. This cooperative hunting technique is similar to that of the moray eel, with the banded sea kraits flushing out prey from narrow crevices and holes, and the partner feeding on fleeing prey. Their main prey item is eel but they have also been observed feeding on small fish such as gobies. They trap their prey in coral crevices using coils of their body. They show sex-based ecological divergence. For example, males being the smaller sex usually forage in shallower water than females and also tend to prey on different kinds of eels, than do their mates.

A deadly game of heads or tails: While probing crevices with their head, they are unable to observe approaching predators and can be vulnerable. The snakes can deter predators, such as larger fish, sharks, and birds, by fooling them into thinking that their tail is their head, because the color and movement of the tail is similar to that of the snake’s head.

Etymology
Laticauda = Latin latus = ‘broad’, +cauda, ‘tail’, in reference to the wide, flat tail
colubrina = Latin colubrinus = ‘having the qualities of a snake’.


Walking along on my cuttlefish arms

Flamboyant Cuttlefish - Metasepia pfefferi
Flamboyant Cuttlefish -Metasepia pfefferi

Flamboyant Cuttlefish – Metasepia pfefferi
Due to the small size of its cuttlebone, it can float only for a short time. This cuttlefish is the only species known to walk or ‘amble’ along the sea floor while rhythmically waving the wide protective membranes on their arms. The arm tips often display bright red coloration to ward off would-be predators. This behavior advertises a poisonous nature, the flesh of this cuttlefish contains a unique toxin.

A toxicology report has confirmed that the muscle tissue of flamboyant cuttlefish is highly toxic, making it only the third cephalopod found to be poisonous. Research has shown the toxin to be as lethal as that of fellow cephalopod the blue-ringed octopus.

Etymology
Meta – Greek meaning “after” or “beyond” is a prefix used in English to indicate a concept which is an abstraction behind another concept, used to complete or add to the latter.
+Sepia – From Ancient Greek “to make rotten”), a cuttlefish, the secretion of a cuttlefish used as ink
Pfeffer – Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks.

Pink Skunk clownfish – Amphiprion Perideraion

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

The magnificent sea anemone – Heteractis 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

Orangutan Crab in Bubble Coral, Achaeus japonicus in Plerogyra sinuosa

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)

Clark’s Anemonefish – Amphiprion 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 Anemone – Heteractis 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.

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’

Sky Blue Phyllidia Nudibranch – Phyllidia 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’

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.

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

Juvenile Warty Frogfish or Clown Frogfish – Antennarius 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’
