longspine thornyhead rockfish

Longspine thornyhead rockfish generally prefer sediment covered seafloor, however on several dives at Astoria Canyon we have found large numbers perched on a variety of rocky substrates. This species, and its close relative the shortspine thornyhead, are both important commercial groundfish. The individual pictured here is approximately 20 cm in length.
