Echinaster luzonicus is normally a six-armed starfish but is often rather asymmetrical in appearance because of its habit of shedding arms. It is somewhat variable in colouring, ranging from red to dark brown. Both these colour morphs were collected off Heron Island in the Great Barrier Reef, and individuals seemed able to change their colour from red to brown and back again, possibly as a response to the amount of ambient light they received.
The length of the shell varies between 3.5 mm and 5 mm.
This is a very small species, light violet with a white transverse band around the body whorl. The shell contains 7-8 whorls, with two smooth, acuminate ones in the protoconch. The whorls are rotund and longitudinally crassicostate. The numerous lirae are tenuous. The violet aperture is irregularly sinuate. The outer lip is incrassate and shows four teeth on the inside region. The sinus is below the suture. The sinus is wide open and moderately deep.

Asthenosoma varium is a sea urchin (an echinoderm, a member of the phylum that also includes star fish). Growing up to 22 cm (8.7 in) in diameter, it lives on sand and rubble sea bottoms in the Indo-Pacific, from the Red Sea to Australia and Southern Japan. Its venom tipped spines, with distinctive globular swellings below the tip, can inflict a painful sting if handled; the pain lasts as long as several hours. This capacity, perhaps coupled with its reddish-brown color, has given it the common name Fire Urchin.
This recently described aglajid variies in dorsal coloration.Spinophallus falciphallus from the Marshall Islands to the Red Sea, is distinguished by its reddish body color, a distinct black or maroon longitudinal line on the foot.
Similar to Spinophallus coronata ( with yellow and maroon spots), Spinophallus falciphallus with lines on the foot.
Pteraeolidia is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Facelinidae The body color of this species is translucent tan but the cerata, which in Hawaii vary from dark purple to lavender to golden brown, give the nudibranch most of its apparent color. This is an extremely elongate species with large, curved arches of cerata along the length of the body.
The back ground colour is white.Tubercles,Rhinophres and gills are purple tiped.The mantle margin is purple or orange in colour. Mexichromis multituberculata feeds exclusively on sponges.
Hypselodoris variobranchia has a deep purple body with a broad solid white border to the mantle. The bulb of the rhinophores is orange, with purple sheaths. The gills may be orange or deep purple. There is a tall gill pocket which is also deep purple in colour. This species has frequently been reported as Hypselodoris bullocki. This is a large nudibranch, reaching 50 mm in length.
Quite similar in appearance to C. geometrica. Two major points of difference are the rhinophore & gill colour and the presence of a few small white rounded nodules on the mantle, each surrounded by a ring of deep magenta (or purple). The gills and rhinophores are a translucent reddish purple colour edged with a dark line of the same colour. Like C. geometrica the anterior mantle waves up and down rhythmically and its underside is a deep purplish colour.
Coryphellina rubrolineata is a relatively large aeolid nudibranch growing to 42 mm in length.The stretched out body has a sharp end at the tail, the dorsal side is covered with a certain amount of extensions called cerata, which size vary from an animal to another. The rhinophores are pointed and look like feathers. The oral tentacles are thin, cylindrical and longer than the rhinophores. The coloration is variable and here’s a description for the two main coloration which can be easily met underwater:
A new described species
Chromodoris lochi is blue or blueish-white with a white margin and typically dark or black lines running down the mantle and the foot. On the mantle, a continuous line runs around the border passing on the outside of the rhinophore and a second median one can be discontinuous. Individuals can reach at least 4 cm in length.There is some variation between individuals in this species, and the gills (retractile) and rhinophores (contractile) range in colour from a translucent straw-color, through to pink and light orange.This species is very similar in appearance to Chromodoris willani, Chromodoris boucheti and Chromodoris dianae and can be difficult to tell apart. Its most distinguishing feature is the uniform colouring of the mantle and the lack of white specks which are present in some of the other species. A recent study showed that more than one species is currently confused amongst Chromodoris lochi.
Ceratosoma tenue can grow to a maximal size of 12 cm length. The body colouration is extremely variable but is always composed of bright colors. However, the body colouration is not a valuable criterion of determination for this species because it can easily be confused with Ceratosoma tribolatum. The physical distinctive criteria are three mantle lobes on the first half of the body on each side and the purple margin of the mantle and foot is a dotted line. Another specificity of many species of Ceratosoma is the kind of “horn” covering the gills, which is like a lure and acts as a defensive chemical weapon that will scare any potential predator who dares to bite this part. The gills and the rhinophores are retractile in internal sheaths.
The moon wrasse (Thalassoma lunare) also known as the cresent wrasse or lyretail wrasse, is a species of wrasse native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of coral reefs and surrounding areas at depths from 1 to 20 m (3.3 to 65.6 ft). Moon wrasses are carnivorous and tend to prey on fish eggs and small sea-floor dwelling invertebrates. This species can reach 45 cm (18 in) in total length. It is of minor importance to local commercial fisheries and can also be found in the aquarium trade.
Pseudanthias pleurotaenia also known as the squarespot anthias, pink square anthias, mirror basslet or squarespot fairy basslet is a species of marine ray-finned fish in the subfamily Anthiinae of the family Serranidae, the groupers and sea basses. This species of Pseudanthias is a reef dwelling fish of the Pacific Ocean. It occasionally makes its way into the aquarium trade and grows to a size of 20 cm in length. The males are deep pink and orange in colour with a large quadrilateral purplish blotch on the flank, a red tip on the posterior margin of the dorsal fin, the caudal fin lobes have mauve tips and there is a reddish stripe which runs from the snout through the eye and through the base of the pectoral fin to the base of the tail. Females and juveniles are yellowish in colour with orange edges to their scales and they have two purple stripes which run from the eye along the lower flanks to the base of the tail.
This is a relatively large member of the Acanthuridae, easily reaching 60 centimeters. The adult has tall dorsal and anal fins, vertical blue lines on its sides, and small blue spots dorsally and ventrally. A broad blue band extends from the eyes to the prominent snout. The coloration of the juvenile is a dingy green with blue spots and lips, later turning deeper blue with purple markings. The fish turns mud-brown while sleeping or when frightened, a form of camouflage.
The hummingbird bobtail squid is a small sized sepia. Its size varies according to the sex; males are no bigger than 3 centimetres (1.2 in) while the female reaches 5 centimetres (2.0 in) length.The global body aspect is compact and rounded. It possesses eight arms and two tentacles, a pair of small lateral fins on the posterior part of the mantle. The background color of the body is translucent with a large number of tiny dark chromatophores. Those later are widely distributed on all the body from arms, head, ventral and dorsal areas of the mantle, except the pair of lateral fins which only the border with the mantle has chromatophores. The external color of the sepia, as we see it, is like a blend of small dark, electric blue and green dots.
The long-snout clingfish is a small type of fish, which can grow up to 5 centimetres (2.0 in).
It has an elongated body and a stretched and spatulate snout. The snout is a criterion for recognizing the sex of the fish, since females have a longer and finer snout than males. This sexual dimorphism reflects a different diet between the two sexes.
Bryaninops natans, known commonly as the redeye goby, is a species of marine fish in the family Gobiidae.
The redeye goby is widespread throughout the tropical waters of the Indo-Pacific area, including Red Sea.
B. natans is a small size that can reach a maximum size of 2.5 cm length.

Hoplophrys oatesi is a very colourful crab that grows from 1.5 to 2 cm. It lives on various species of soft coral in the genus Dendronephthya. It camouflages itself by mimicking the colours of the polyps among which it hides. It adds further camouflage by attaching polyps to its carapace. Colours vary depending on the colour of the coral, and may be white, pink, yellow or red.
