Characteristics

Sebastes species share a number of distinctive characteristics. They possess a spiny dorsal fin, a strong, robust body, and a large head with a prominent snout.

Some species are known to migrate seasonally between shallower and deeper waters. The specific environmental preferences of each species vary, but they generally thrive in areas with abundant food sources and suitable shelter.
