Description

The squarespot rockfish is a rockfish (Sebastidae) from the eastern Pacific, from California to Baja California. The species reaches about 29 cm and has an olive-brown body with several dark, square blotches on the back, to which the name refers. It inhabits shallow rocky reefs and feeds on zooplankton and small invertebrates. Like all rockfishes the species is viviparous: after internal fertilisation the female gives birth to large numbers of larvae. The fin spines are venomous and can deliver a painful sting when handled. The species is regularly eaten and caught in recreational fisheries.
