Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Species of Iniistius are called razorfish in allusion to their compressed bodies and the sharp leading edge of their forehead and snout, specialisations for quick entry into sand (Randall 2007).

Juveniles are found in coastal waters along reef edges on sand or rubble, or open patches on reef. Adults occur mainly in deep outer reef habitats in small loose group along sand ridges (Kuiter and Tonozuka 2001).

Justification
This species was originally known from one specimen from Hong Kong. It is now also known from 76 additional specimens from Vietnam, from a fish importer in Sweden. There is little published information on its biology and ecology, population status or impact of potential threats. It is therefore listed as Data Deficient.

Wikipedia

Iniistius trivittatus

Iniistius trivittatus is a species of wrasse currently only known from the Pacific waters off Hong Kong and Taiwan. This species inhabits reefs from the surface to 10 m (33 ft) deep. It can reach 30 cm (12 in) in total length.[2]

It is deep bodied and extremely laterally compressed as in all members of its genus. It is distinctively coloured, generally pale yellow with three broad, dark, vertical bars on its body. A further diagnostic trait is the presence of a deep notch between the first two spines of the dorsal fin.[2]
