Identification
Dorsal Fin: X, 15
Anal Fin: III, 7
Pectoral Fin: 14

Lateral Line: 48-54
Gill Rakers: 6-8 (upper), 11-15 (lower) on first arch
Body robust and laterally compressed. Steeply sloping head profile. Dorsal fin continuous with no obvious notch between spiny and soft portions. Anal fin much smaller than dorsal fin. Caudal fin is typically truncate to slightly emarginate. The mouth is large and terminal, with the lower jaw often slightly projecting. Jaws bear villiform teeth, with an inner band of enlarged canines. Scales are ctenoid and cover the body and much of the head. The lateral line is continuous and curves gently along the upper body.
Color
Body and fins yellowish brown, becoming more yellow on the head and nape. A dark blotch is variably expressed on the snout. The caudal fin is often yellowish. Caudal peduncle often with a faint blotch. The fins often have a bluish tint, especially the ventral fins.

Coral reefs in water less than 20m.

Other Notes
More study with complete taxon sampling, many specimens from all over the Caribbean, and for multiple genes are required to determine just how many “species” of Hypoplectrus actually occur in the Caribbean Sea. The species are morphologically almost identical, and have weak genetic signatures indicating a recent radiation.
