Whitelined Rockcod, Anyperodon leucogrammicus (Valenciennes 1828)

Other Names: Slender Grouper, Whitelined Cod, White-lined Cod, White-lined Rockcod, White-lined Rock-cod

A Whitelined Rockcod, Epinephelus leucogrammicus (formerly Anyperodon leucogrammicus), at Kri Eco, Raja Ampat, West Papua, Indonesia. Source: Paddy Ryan / http://www.ryanphotographic.com/. License: All rights reserved

A slender greenish to brownish-grey rockcod with reddish spots, 3-4 irregular pale stripes along the sides, and a pointed snout. The distinctive blue and gold striped juveniles mimic some small lined wrasses of the genus Halichoeres, such as initial phase Hoeven's Wrasse, Halichoeres melanurus.

In a genetic study of epinepheline groupers, Ma & Craig (2018) concluded that this species belongs in the genus Epinephelus

Whitelined Rockcod, Anyperodon leucogrammicus (Valenciennes 1828)

More Info


Recorded in Australia from Coral Bay to Kendrew Island, and Rowley Shoals, Scott Reef, Western Australia, and Ashmore Reef, Timor Sea, to the Great Barrier Reef, Queensland, and reefs in the Coral Sea; also at the Australian territories of Cocos (Keeling) Islands and Christmas Island in the eastern Indian Ocean. Elsewhere the species is widespread in the tropical Indo-Pacific from the Red Sea south to Mozambique, east to the Phoenix Islands, north to Japan, and south to Australia (southern Queensland and Heron Island) - also at Oman and Aldabra (Seychelles).
Inhabits coral rich areas in lagoons and on seaward reefs. 


Dorsal fin XI, 14-16; Anal fin III, 8-9.
Body elongate, greatest depth 3.1-3.7 in SL; head pointed, 2.3-2.5 times in SL; interorbital region narrow, dorsal head profile almost straight; preorbital narrow, depth 14-17 times in HL; snout distinctly longer than eye; preopercle rounded, finely serrate, lower serrae only slightly enlarged, lower edge fleshy; ventral edge of interopercle with a shallow indentation: opercular spines small, upper edge of operculum distinctly convex; maxilla reaching beyond eye, exposed part covered with tiny cycloid scales; rear end of maxilla without bony process; supramaxilla well-developed; palatines without teeth; canines at front of jaws rudimentary or absent. Caudal fin rounded; pelvic fins short, not reaching anus.


Feeds mainly on fishes, and also consumes crustaceans.


Although not commercially targeted, the Whitelined Rockcod occasionally appears in the live fish trade in Hong Kong. The distinctive blue and gold striped juveniles are targeted for the aquarium trade.
