New species and records of deep-water Cirratulidae (Polychaeta) from off Northern California
Polychaetes of the family Cirratulidae are among the most important macrofaunal invertebrates in deep-sea benthic communities off northern California. The genus Chaetozone includes several species that are among the dominant species in depths of 2400-3200 m. Four of the most common species of Chaeto...
