Ribboned Sweetlips Plectorhinchus polytaenia occurs in the tropical Indo-West Pacific from West Coast India to Australia in a depth range from 5-40m on coastal and seaward reefs, max. length 50cm. The species is found singly, in small groups under ledges or large resting aggregations by day, foraging for small invertebrates at night. Adults are found on deep, current-prone slopes with rich invertebrate growth; juveniles on sheltered reefs nearby. \nBluestreak Cleaner Wrasses Labroides dimidiatus usually occur in pairs in the tropical Indo-Pacific in a depth range from 1-40m, usually 1-30m, max. length 14cm. The species creates 'cleaning stations' to which fishes come to have crustacean ectoparasites and mucus removed. Cleaning intensity is not related to client size or commonness. Even hands of divers will be cleaned if presented to the cleaning station! \nThis specimen was encountered in the Triton Bay, Kaimana Regency, West Papua Province, Indonesia, 3°54'50.604 S 134°6'0.828 E at 15m depth.

Maiden Goby Valenciennea puellaris occurs in the Indo-Pacific from the Red Sea to Samoa, north to southern Japan, south to the Great Barrier Reef and New Caledonia in a depth range from 2-84m, max. length 20cm. \nThe monogamous species inhabits sandy areas of clear lagoon and seaward reefs. Maiden Goby occurs in pairs and use burrows as refuge. The burrow is shallow, only a few cm, and made under large pieces of rubble. \nTriton Bay, West Papua Province, Indonesia,\n3°54'52.062 S 134°7'21.384 E at 12m depth

Bigfin Reef Squids are easy to distinguish from other squids in that they possess thick and muscular oval fins that extend around almost the entire mantle. Because of these fins, bigfin reef squids are sometimes mistaken for cuttlefish. The bigfin reef squid is the most widespread species in the genus Sepioteuthis. It is found in temperate and tropical regions of the Indian Ocean and the Western Pacific Ocean.\nAt night, when the Bigfin Reef Squids are most active, they are commonly found in shallow areas from 0-100m around reefs, sea grass beds, sandy bottoms, or rocky shorelines. They surface at night, as it is less likely to be detected by predators. During the day, they generally move to deeper waters or near any form of cover, such as floating driftwood, reefs, rocks, or grasses.\nSquids have speedy colour-changing abilities as their pigment cells, the chromatophores, rapidly change size and colour and the visual effect is enhanced by light reflecting cells, the iridocytes. They can shoot ink (dark melanin pigment) to confuse predators and aide in escapes. \nTriton Bay, West Papua Province, Indonesia, 3°56'17.7941 S 134°7'10.2802 E at 1m depth

The outer side of the shell is designed to be encrusted by all kind of sessile animals. Max. recorded size is 137cm and 500kg! In addition the ecological role of Tridacna gigas, shells of this bivalve species are useful bioarchives for past climate and environmental reconstructions.
