species of fish
The tiger grouper (Mycteroperca tigris) 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 warmer waters of the western Atlantic Ocean.
Description
The tiger grouper has a body which is elongate, robust and compressed, its depth being the no greater at the origin of the dorsal fin as it is at the origin of the anal fin, and a large mouth. The standard length is 3.1 to 3.6 times the depth of the body. The preopercle is rounded and does not have a lobe at its angle. The dorsal fin contains 11 spines and 15-17 soft rays while the anal fin contains 3 spines and 11 soft rays. The membranes between the dorsal fin spines are obviously notched. The caudal fin is a straight in juveniles and slightly concave in adults. The upper body is dark and there are 9 to 11 thin, pale oblique lines. It is capable of dramatic changes in colour, as well as lightening or darkening its colour.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Tiger grouper”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q2755475.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
