Longfin grouper
species of fish
The longfin grouper (Epinephelus quoyanus), also known as the longfin rockcod, bar-breasted rock-cod, Gilbert's rock-cod, honeycomb rockcod, spotted groper or wirenet cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Western Pacific Ocean.
Description
The longfin grouper has a body with a standard length which is 2.8 to 3.2 times its depth. The dorsal profile of the head is smoothly curved. The preopercle is rounded or subangular while the gill cover has a nearly straight upper edge. The dorsal fin contains 11 spines and 16-18 soft rays while the anal fin has 3 spines and 8 soft rays. The caudal fin is rounded while the pectoral fin is around twice the length of the head. The overall colour is whitish on the head, body and fins and it is marked with many sizeable closely set hexagonal to roundish dark brown to blackish spots. On the upper head and body the spots are closer together and form a reticulated pattern while on the lower head and body the spots are more widely spaced and they are less well defined. There is a pattern of similar dark spots on dorsal, anal and caudal fins.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Longfin grouper”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 5, 2026. The linked authority identifier is Q303990. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
