Sebastes rastrelliger is a species of fish belonging to the rockfish family, Sebastidae. It is a common inhabitant of coastal waters, particularly in the northeastern Pacific Ocean. The species is characterized by its distinctive appearance and ecological role within its marine environment.
Description & Characteristics
Sebastes rastrelliger is a moderately sized fish, reaching a maximum length of 56.0 cm. Its body is elongated and compressed laterally, with a prominent dorsal fin that extends nearly the entire length of its back. This fin exhibits a characteristic spiny structure, a common trait among rockfishes.

Habitat and Occurrence
Sebastes rastrelliger thrives in shallow coastal waters, with a depth range extending from the surface down to 46.0 meters. This species is commonly found in the nearshore environment, particularly in rocky reefs, kelp forests, and sandy bottoms. Its distribution is primarily confined to the northeastern Pacific Ocean, where it is a prevalent presence in the marine zones of the continental shelf and upper slope.
Taxonomy
Sebastes rastrelliger belongs to the Class: Teleostei, Order: Perciformes, and Family: Sebastidae. This taxonomic placement reflects its evolutionary lineage and shared characteristics with other rockfish species. Its classification within the Order Perciformes highlights its shared traits with a vast array of diverse fish species, including perch, bass, and wrasses.
Feeding
