Other Names: Griffiths’ Razor Fish

A relatively deep-bodied pale greyish razorfish becoming whitish below, with 1-6 small blue-edged black spots clustered above the pectoral-fin tip, an elongate reddish-brown patch just below the middle of the caudal peduncle, and vertical blue lines on the gill cover. Some individuals (possibly males) have a broad oblique pale blue band containing many small black spots from high on the nape to above the gill cover.

Species of the genus Iniistius have highly compressed bodies and a steep forehead with a firm knife-like anterior edge - enabling them to easily dive into the sand when threatened.

More Info


Known from the Exmouth region of Western Australia, and the Australian Territory of Christmas Island in the eastern Indian Ocean. Elsewhere the species is widespread in the Indian Ocean. Inhabits open sandy areas, diving into the sand when threatened and to sleep at night.


Dorsal fin IX, 12; Anal fin III, 12; Pectoral fin 12; Principal caudal rays 12, uppermost unbranched, upper procurrent caudal rays 6, lower procurrent caudal rays 5; Gill rakers 19-20; Lateral line scales 19-20 + 5-6; Vertebrae  25.
Body relatively deep, depth 2.5-2.6 in SL; dorsal profile of snout nearly vertical; dorsal profile of the head almost evenly convex; dorsal-fin origin above posterior edge of the orbit, first two spines slender and flexible, the first slightly longer, 2.45-2.55 in HL; space between second and third dorsal-fin spines more than twice that between first and second spines; cheek naked except for curved oblique row of 6 small scales from behind to below eye; 1 or 2 small scales dorso-anteriorly on the opercle. Fins short, origin of the dorsal fin over posterior edge of orbit.


Pale grey, scale edges dorsally on body grey-brown; head grey-brown, operculum suffused with orange, with vertical blue bands; a broad oblique pale blue band containing numerous small black spots from interorbital space to above opercle; one to several black spots, edged in pale blue, on side of body above tip of pectoral fin; a dusky streak below posterior end of maxilla and lower lip; orangish patch on side of caudal peduncle, each scale with a pale blue spot; median fins bluish grey; pectoral fins orange.


The three type specimens of Iniistius griffithsi were taken by handline from 120 m off Mauritius. Despite their relatively small size, fishes of the genus Iniistius are highly esteemed as food fishes. They are often consumed by the fishermen themselves, therefore not often found in markets (Randall 2007).


The species is named griffithsi for the collector, Jeremy Griffiths.
