Description

The rosethorn rockfish is a scorpionfish of the rockfish family (Sebastidae) from the north-eastern Pacific. The species grows to about 41 cm and has a reddish body with a few pale blotches on the back. It lives on soft bottoms and rocky depths of the continental shelf and slope and is often caught on commercial longlines below about 108 metres. Rockfishes are viviparous: fertilisation is internal and the female produces larvae. As a predator it feeds on small crustaceans and small fishes. The fin spines are venomous and give a painful puncture wound; handle a caught specimen with care.
