Phyllodesmium colemani uses camouflage and hides amongst the polyps of Tubipora musica on which it feeds. The length of the slug is 18 mm. This species contains zooxanthellae which are stored in aggregations of terminal chambers all over the ceratal wall.
A relatively small species, few whitetip reef sharks are longer than 1.6 m (5.2 ft). The maximum length this species attains is often given as 2.1 m (6.9 ft), though this was originally based on visual observations and may be dubious. The maximum reported weight is 18.3 kg (40 lb). The whitetip reef shark has a slim body and a short, broad head. The snout is flattened and blunt, with large flaps of skin in front of the nares that are furled into tubes. The eyes are small and oval with vertical pupils and prominent ridges above, and are often followed by a small notch. The mouth has a distinct downward slant (imparting a disgruntled expression to the shark), with short furrows at the corners. There are 42–50 tooth rows in the upper jaw and 42–48 tooth rows in the lower jaw. Each tooth has a single narrow, smooth-edged cusp at the center, flanked by a pair of much smaller cusplets.
Whale sharks have a mouth that can be 1.5 m (4.9 ft) wide, containing over 300 rows of tiny teeth and 20 filter pads which it uses to filter feed. Unlike many other sharks, whale sharks’ mouths are located at the front of the head rather than on the underside of the head. Whale sharks have five large pairs of gills. The head is wide and flat with two small eyes at the front corners. Whale sharks are dark grey with a white belly. Their skin is marked with pale grey or white spots and stripes which are unique to each individual. The whale shark has three prominent ridges along its sides, which start above and behind the head and end at the caudal peduncle. Its skin can be up to 15 cm thick and is very hard and rough to the touch. The shark has two dorsal fins set relatively far back on the body, a pair of pectoral fins, a pair of pelvic fins and a single medial anal fin. The tail has a larger upper lobe than the lower lobe (heterocercal). The whale shark’s spiracles are just behind its eyes.
Plectorhinchus gibbosus, commonly known as the Harry sweetlips, is a marine fish native to the Western Pacific and Indian Oceans.
Petroscirtes variabilis, the variable sabretooth blenny, variable fangblenny, or the variable blenny, is a species of combtooth blenny found in the western Pacific and Indian ocean. This species reaches a length of 15 centimetres (5.9 in)
The caudal fin of the ocean sunfish is replaced by a rounded clavus, creating the body’s distinct truncated shape. The body is flattened laterally, giving it a long oval shape when seen head-on. The pectoral fins are small and fan-shaped, while the dorsal fin and the anal fin are lengthened, often making the fish as tall as it is long. Specimens up to 3.2 m (10.5 ft) in height have been recorded.
Mobula eregoodootenkee (the pygmy devil ray or longhorned mobula) is a species of ray in the family Mobulidae. It is endemic to the Indian Ocean and central-west Pacific Ocean. It ranges from South Africa in the west to the Philippines in the east, north to Vietnam, and south to the northern coast of Australia.
Inimicus didactylus, also known as demon stinger or devil stinger, is a member of the Inimicusgenus of venomous fishes, closely related to the true stonefishes. It can reach a body length of 25 cm (10 in) and is irregularly surfaced with spines and a knobby appearance. The fish has venomous spines to ward off enemies. The fish are nocturnal, and often dig themselves partially into the sandy seabed during the day. The body is red or sandy yellow and well camouflaged on sandy and coral seabeds.
The goldspot seabream is a medium-sized fish which can grow up to a maximum length of 30 cm, however the commonly observed size is 20 cm. Its body is compressed laterally, the snout is pointed and the tail is forked. The background coloration is silver-grey with golden horizontal lines on the sides, these later are topped by dark horizontal lines. Its fins have pinkish shades, a yellow mustache-like line overcomes the upper lip, the junction of the pectoral fins to the body is marked with yellow and also along the outer edge of the operculum. A golden yellow spot located on the back at the termination of the dorsal fin is a hallmark of this species. In proportion to body size, the eyes are quite large.
Dugongs are found in warm coastal waters from the western Pacific Ocean to the eastern coast of Africa, along an estimated 140,000 kilometres (86,992 mi) of coastline between 26° and 27° degrees to the north and south of the equator. Their historic range is believed to correspond to that of seagrasses from the Potamogetonaceae and Hydrocharitaceae families. The full size of the former range is unknown, although it is believed that the current populations represent the historical limits of the range, which is highly fractured.Today populations of dugongs are found in the waters of 37 countries and territories. Recorded numbers of dugongs are generally believed to be lower than actual numbers, due to a lack of accurate surveys. Despite this, the dugong population is thought to be shrinking, with a worldwide decline of 20 percent in the last 90 years. They have disappeared from the waters of Hong Kong, Mauritius, and Taiwan, as well as parts of Cambodia, Japan, the Philippines and Vietnam. Further disappearances are likely.
Dactylopus kuiteri, known commonly as the Kuiter’s dragonet, is a species of marine fish in the family Callionymidae.
The Kuiter’s dragonet is widespread throughout the tropical waters of the central Indo-Pacific region and particularly around Indonesia.
The grey reef shark has a streamlined, moderately stout body with a long, blunt snout and large, round eyes. The upper and lower jaws each have 13 or 14 teeth (usually 14 in the upper and 13 in the lower). The upper teeth are triangular with slanted cusps, while the bottom teeth have narrower, erect cusps. The tooth serrations are larger in the upper jaw than in the lower. The first dorsal fin is medium-sized, and no ridge runs between the second dorsal fin and it. The pectoral fins are narrow and falcate (sickle-shaped).
Arothron nigropunctatus is a small sized fish which grows up to 33 cm (1 ft) length. Its body is oval shape, spherical and relatively elongated. The skin is not covered with scales. The fish has no pelvic fin and no lateral line. The dorsal fin and the anal fin are small, symmetric and located at the end of the body. Its snout is short with two pairs of nostrils and its mouth is terminal with four strong teeth.
The main body of the octopus is normally 8 centimeters (3 in) long and including the arms, approximately 15 centimeters (6 in) long. The octopus displays a typical color pattern with dark ramified lines similar to veins, usually with a yellow siphon. The arms are usually dark in color, with contrasting white suckers. In many color displays, a lighter trapezoidal area can be seen immediately below the eye.
Aluterus scriptus is a medium size fish which can grow up to 110 cm (3.6 ft) in length. The body shape looks like an elongated oval, strongly compressed. Its background body coloration is olive-brown or grey depending on its surrounding environment, irregular blue lines and spots are distributed on the body mixed with some black spots mainly on the head. The colors may quickly vary depending on background similar to an octopus’s. Fish observed in the Virgin Islands might lie flat on the sand and become pure white or change to any of the other representative colors. The mouth is small and at the end of its pointed snout. Like all the Tetraodontiformes, it has no pelvic fin but has two particular dorsal spines; the first anterior one is long, slender and erectile, located just over the eyes, the second is small and not easy to see but it locks the first one when it is erected.[3] The rounded caudal fin is quite long and can be displayed as a fan.
