蓝海星，蓝指海星

The variation (“polymorphism”, in this case, a “color morph”) most commonly found is pure, dark, or light blue, although observers find the aqua, purple, or orange variation throughout the ocean. These sea stars may grow up to 30 cm (11.8 in) in diameter, with rounded tips at each of the arms; some individuals may bear lighter or darker spots along each of their arms. Individual specimens are typically firm in texture, possessing the slightly tubular, elongated arms common to most of other members of the family Ophidiasteridae, and usually possessing short, yellowish tube feet. An inhabitant of coral reefs and sea grass beds, this species is relatively common and is typically found in sparse density throughout its range. Blue stars live subtidally, or sometimes intertidally, on fine (sand) or hard substrata and move relatively slowly (mean locomotion rate of 8.1 cm/min).

The appearance of this sea star can be highly variable (colors, plates, presence of plates on the central disc, armpits…), and its identification using picture can be difficult, as many other species (like Fromia nodosa) can have a very similar aspect.

短刺礼服海胆、高腰海胆、蓝礼服海胆

It is a small regular sea urchin of almost spherical shape, whose diameter of the shell (called “test”) can go up to 5 cm1. The quills (“radioles”) are fine and fairly short, not exceeding 2 cm, densely arranged and ringed in black or brown with the white tip. These radioles are arranged in five times two well delimited bands (called “ambulacraires”), all the quills of each band being as “brushed” in the same direction. These bands alternate with ten other bands without spines (perradial and interradial bands), most often brightly colored deep blue (most often Duck blue, Klein blue, royal blue or verdigris, but sometimes also almost greenish black), and whose appearance is reminiscent of velvet. It is in fact a carpet of small denticulate globiferous pedicellars.

长刺海胆

Diadema paucispinum is a small sea urchin with very long, moveable spines which are slender and sharply pointed. They can be up to 25 cm (10 in) long and about four times the diameter of the test. The primary spines are bluish-black in colour, often with pale bands in younger individuals. The shorter secondary ones are brittle and venomous and easily break off in the skin. There are photosensitive spots in the urchin’s epidermis and if a shadow falls on the animal, it angles its secondary spines towards the intruder. These can cause a painful sting if they come into contact with bare skin. Near the apex of the test is a clearly visible anus surrounded by an orange ring and raised on a small projection. Radiating from this are five narrow, bright blue lines.

The ribbon eel (Rhinomuraena quaesita), also known as the leaf-nosed moray eel or bernis eel, is a species of moray eel, the only member of the genus Rhinomuraena. What is now known as R. quaesita also includes the former R. amboinensis. R. quaesita was used for blue ribbon eels and R. amboinensis for black ribbon eels, but these are now recognized as the same species. The ribbon eel is found in lagoons and reefs in the Indo-Pacific ocean, ranging from East Africa to southern Japan, Australia and French Polynesia. This species is widely distributed and is frequently seen by divers in Indonesian waters with their heads and anterior bodies protruding from crevices in sand and rubble habitats from very shallow to about 60 m. Although generally placed in the moray eel family Muraenidae, it has several distinctive features leading some to place it in its own family, Rhinomuraenidae.

The yellowface angelfish grows to a maximum length of 38 centimetres (15 in) and is laterally compressed. The mouth is just above the tip of the snout. The fins are large and rounded and are yellow, some edged with blue round the margins. The dorsal fin is set just in front of the caudal region, has a distinctive black eyespot at the base and has 13–14 spines and 16–18 soft rays. The anal fin has 3 spines and 16–18 soft rays. The scales are pale blue edged with yellow giving a reticulated pattern. The face is yellow with a dense network of brilliant blue lines on the bottom half and a plain yellow mask around the eyes. Juveniles are quite differently coloured with 6 vertical white bars separated by pale blue lines and a caudal fin barred in 2 shades of blue.

It is similar in shape to a number of other large jacks and trevallies, having an oblong, compressed body with the dorsal profile slightly more convex than the ventral profile, particularly anteriorly. This slight convexity leads to the species having a much more pointed snout than most other members of Caranx. The dorsal fin is in two parts, the first consisting of 8 spines and the second of 1 spine followed by 21 to 24 soft rays. The anal fin consists of 2 anteriorly detached spines followed by 1 spine and 17 to 20 soft rays.The pelvic fins contain 1 spine and 20 soft rays.The caudal fin is strongly forked, and the pectoral fins are falcate, being longer than the length of the head. The lateral line has a pronounced and moderately long anterior arch, with the curved section intersecting the straight section below the lobe of the second dorsal fin. The curved section of the lateral line contains 55-70 scales while the straight section contains 0 to 10 scales followed by 27 to 42 strong scutes. The chest is completely covered in scales. The upper jaw contains a series of strong outer canines with an inner band of smaller teeth, while the lower jaw contains a single row of widely spaced conical teeth. The species has 25 to 29 gill rakers in total and there are 24 vertebrae present.The eye is covered by a moderately weakly developed adipose eyelid, and the posterior extremity of the jaw is vertically under or just past the anterior margin of the eye.Despite their wide range, the only geographical variation in the species is the depth of the body in smaller specimens.
