Longfin grouper
The longfin grouper is a small reef predator with a light "honey" colour and a dense pattern of dark hexagonal or rounded spots on the head, body and fins. On the upper body the pattern looks more like a network; lower down the spots are fewer and less distinct. It is usually sluggish and often "sits" on the bottom resting on its long, fleshy pectoral fins; it feeds on small fish, crustaceans and worms.
Epinephelus quoyanus
Marbled sea cucumber
The marbled sea cucumber (Pearsonothuria graeffei) is a bottom-dwelling holothurian of the tropical Indo-Pacific. The body is elongated and cylindrical, with light (creamy or greyish-brown) colour and many dark dots and patches forming a "marbled" pattern; low papillae are visible on the skin. It feeds by sifting the surface layer of sediment and extracting organic matter (detritus). Under strong stress it may release sticky threads (Cuvierian tubules) that contain toxic substances.

Pineapple sea cucumber
The pineapple sea cucumber is a very large holothurian of the family Stichopodidae, living on sandy areas and among coral reefs in the Indo-Pacific. It is notable for its size and firm, "armoured" body with many pointed star-shaped papillae in rows of 2–3. Coloration is usually warm grey-brown to reddish-orange with darker patches. It feeds on organic matter from the sediment by passing the surface layer of the bottom through its mouth.
