Trachyscorpia

Trachyscorpia is a genus of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae.

Trachyscorpia was first described as a genus by the Lithuanian-born American ichthyologist Isaac Ginsburg in 1953 with Scorpaena cristulata, a species described by the American ichthyologists George Brown Goode and Tarleton Hoffman Bean in 1896 from off Georgia, designated as its type species.

[3] There are currently seven recognised species in this genus:[4] Trachyscorpia is characterised by having a large head, which is almost half the length of the body, with a short snout and robust bones with strong spines.

In larger fish the lower pectoral fin rays are fleshy, Thera are rough scales on cheek, in the intraorbital space and behind the eyes while the lateral line is complete, it reaches the base of the caudal fin, and has tubed scales.

[4] Trachyscorpia thornyheads are thought to be oviparous and, like other taxa in the tribe Sebastolobini, the females likely extrude internally fertilised eggs in gelatinous masses which float.
