Thromidia catalai is a sea star species. It was first described by Pope and Ross Robert Mackerras Rowe circa 1977. Thromidia catalai belongs to the genus Thromidia in the family Mithrodiidae.
Growing to a maximum diameter of 26 cm (10 in), Echinaster callosus has a small central disc and five slender cylindrical arms. The aboral (upper) surface is densely covered by warty protuberances. The colour of this starfish is variable, but may be orange, pink or violet, with the warts being a contrasting colour, usually white, pink, red or mauve. The white warts often occur in bands, particularly towards the tips of the arms. There are small yellowish-green retractable pedicellaria between the warts. The oral (under) surface of the starfish is white with white warts. There are ambulacral grooves on the underside of the arms along which food is passed by ciliary action. The tip of each arm bears an eyespot, as well as a bundle of suckers.
The Choriaster granulatus is a species of Asteroidea described by Christian Frederik Lütken in 1869. The Choriaster granulatus belongs to the genus Choriaster, and is known as the Oreasteridae. There are no subspecies listed.
The body form of the crown-of-thorns starfish is fundamentally the same as that of a typical starfish, with a central disk and radiating arms. Its special traits, however, include being disc-shaped, multiple-armed, flexible, prehensile, and heavily spined, and having a large ratio of stomach surface to body mass. Its prehensile ability arises from the two rows of numerous tube feet that extend to the tip of each arm. In being multiple-armed, it has lost the five-fold symmetry (pentamerism) typical of starfish, although it begins its life cycle with this symmetry. The animal has true image forming vision.
Thylacodes is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. The species in this genus were previously placed in the genus Serpulorbis.
Unlike some other vermetids, the species in this genus have no operculum.
Terebra is a genus of small to large-sized predatory sea snails, marine gastropod mollusks in the family Terebridae, the auger snails.
The shells of these quite uncommon cowries reach on average 50–70 millimetres (2.0–2.8 in) of length, with a minimum size of 23 millimetres (0.91 in) and a maximum size of 105 millimetres (4.1 in). They are very variable in pattern and colour. The dorsum surface is smooth and shiny, the basic color is brown or yellowish brown, with three or four yellow or light brown transversal bands. The margins, the base and the teeth are completely dark brown or black. Also the teeth are dark brown, but the teeth spacing is clearer or white. In the living cowries the mantle is greyish or black, with long cylindrical papillae. Mantle and foot are well developed, with external antennae. The lateral flaps of the mantle may hide completely the shell surface and may be quickly retracted into the shell.
Phalium bandatum, common name the banded bonnet, is a species of sea snail, a marine gastropod mollusk in the family Cassidae.
There is one subspecies: Phalium bandatum exaratum (Reeve, 1848)
The size of an adult shell varies between 40 mm and 140 mm.
The shells of these quite common cowries reach on average 65–70 millimetres (2.6–2.8 in) of length, with a minimum size of 50 millimetres (2.0 in) and a maximum size of 120 millimetres (4.7 in). They are egg-shaped (hence the Latin name ovum, meaning egg). The surface of the shell is smooth, shiny and completely snow white, with a dark reddish-purple interior, visible through the wide and long aperture, which bears teeth on one side only. In the living cowries the mantle is black, with a pattern of small white spots in adults, while juveniles resemble some toxic nudibranchs of the genus Phyllidia owing to their orange yellow sensorial papillae. The lateral flaps of the mantle usually hide completely the white surface, but the mantle is quickly retracted into the shell opening when the cowry is disturbed.
Oliva oliva is a species of sea snail, a marine gastropod mollusc of the family Olividae, the olive snails.
This is the type species of the genus Oliva.
Murex ternispina (also known as Murex Nigrospinosus) is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
The size of the shell varies between 40 mm and 90 mm.
The somewhat thick shell is ovate and inflated. It has a whitish ground color, varied and spotted with square spots, of a yellow more or less reddish, alternating upon the transverse ribs, with other spots of a dull white. The short spire is composed of six convex whorls, slightly flattened above, banded with ribs equally convex, wide, not distant, and divided by narrow, shallow furrows. The aperture is somewhat narrow, toothed upon both edges, colored yellow within. The outer lip is dilated, particularly towards the base, and forms externally a very thick convex margin, the external part of which is sharp, undulated, and its internal surface furnished with ten or twelve transverse, distant teeth, resembling folds. The inner lip consists of a smooth plate, convex and white, which partially covers the body of the shell. The columella presents a pretty deep emargination, above which are observed several transverse thick folds, and some others, less numerous, more oblique, and less distinctly marked.
The shells of these very common cowries reach on average 35–45 millimetres (1.4–1.8 in) of length, with a minimum size of 20 millimetres (0.79 in) and a maximum size of 100 millimetres (3.9 in). The shape is usually pear-shaped, the dorsum surface is smooth and shiny and may be pale or dark brown, with several small white spots. The margins and the extremities are clearer, while the base is generally white, with a wide sinuous aperture and long labial teeth. The margins show also numerous thin vertical whitish lines. The juvenile forms have two-three clearer trasversal bands on the shell dorsum. These shells are quite similar and may be confused with the shells of Lyncina camelopardalis. In the living cowries the mantle is grey-brown and almost transparent, with long whitish tree-shaped papillae. Mantle and foot are very well developed, usually with external antennae.
Leporicypraea mappa (previously known as Cypraea mappa), common name the map cowry, is a species of large sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.
This is considered an economically important species in the Indo-West Pacific, where it is usually collected both for food and for shell trading.
Lambis scorpius, common name the scorpion conch or scorpion spider conch, is a species of large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
The size of an adult shell varies between 95 mm and 220 mm.
This quite common species looks very similar to Cypraea tigris, but its shell is more slender and lighter. The shells of Cypraea pantherina reach on average 57–65 millimetres (2.2–2.6 in) of length, with a minimum size of 37 millimetres (1.5 in) and a maximum size of 118 millimetres (4.6 in). The shape of these shells is roughly elongate-pyriform. They are quite heavy for their size. The dorsum surface is smooth and shiny, usually whitish or pale brown, densely covered with dark brown circular spots. A blurred longitudinal reddish line runs along the midline where the two halves of the mantle meet in life.

The spicules (microscopic calcareous structures that project through the skin) are a mixture of anchors and perforated plates with large holes.

Quadrella maculosa is a species of crab from the Trapeziidae family. The scientific name of the species was first validly published in 1898 by Alcock.
Sea spiders have long legs in contrast to a small body size. The number of walking legs is usually eight (four pairs), but species with five and six pairs exist. Because of their thin body and legs, no respiratory system is necessary, with gases moving by diffusion. A proboscis allows them to suck nutrients from soft-bodied invertebrates, and their digestive tract has diverticula extending into the legs.
