The Gopher Rockfish, Roundhead Rockfish, scientifically known as Sebastes carnatus, is a species of rockfish found in the northeastern Pacific Ocean. These fish are characterized by their distinctive round heads and are known to inhabit a variety of rocky habitats, often seeking shelter in crevices and caves.
Description and Characteristics
Sebastes carnatus, commonly referred to as the Gopher Rockfish or Roundhead Rockfish, can reach a maximum size of 39.0 cm. They are distinguished by their round heads, a feature that contributes to their common name, the Roundhead Rockfish. These fish are often found in a range of colors, including browns, reds, and oranges, which help them blend seamlessly into their rocky surroundings.
Habitat and Occurrence
Sebastes carnatus is a common inhabitant of the subtidal, sublittoral, and infralittoral zones, extending into the deep zone of the oceans. This means they can be found in marine environments from the lower limit of the intertidal zone to the shelf edge, reaching depths of around 200 meters. This makes them a species of the neritic zone, a marine environment located over the continental shelf. The Gopher Rockfish, Roundhead Rockfish prefers rocky habitats, seeking refuge within kelp forests, rock crevices, rocky outcrops, rock ledges, rocky reefs, underwater caves, and underwater caverns. Their adaptability to these diverse environments allows them to thrive in the northeastern Pacific Ocean.
Taxonomy
Sebastes carnatus belongs to the Class: Teleostei, Order: Perciformes, and Family: Sebastidae. The Teleostei class encompasses a vast number of fish species, including those with bony skeletons, and the Perciformes order is one of the most diverse, encompassing a significant portion of the world’s fish species. The Sebastidae family, commonly known as rockfishes, includes many species adapted to living in rocky environments, exhibiting a variety of colors and patterns for camouflage.
