Blepsias cirrhosus, the silverspotted sculpin, is a species of sculpin belonging to the subfamily Hemitripterinae of the family Agonidae. This species is found the northern Pacific Ocean from the Sea of Japan and Alaska to San Miguel Island off southern California.

Taxonomy

Blepsias cirrhosus was first formally

monospecific genus Blepsias for T. cirrhosus so it is the type species of that genus.[4] The specific name cirrhosus means "curled" or "bearing tendrils", an allusion to the elongated, whiskery barbels on the snout and chin.[5]

Description

Blepsias cirrhosus has a deep, compressed body which is covered in papillae which enclose a small spine that is embedded in a bony plate in the skin. There are

standard length is 20 cm (7.9 in).[2]

Distribution and habitat

Blepsias cirrhosus is found in the North Pacific Ocean which has a range which extends from the Sea of Japan north to the Bering Sea and south along the western coast of North America as far as San Simeon in central California. It is a demersal fish found at depths of 0 to 150 m (0 to 492 ft) in intertidal, and more commonly subtidal areas, typically no deeper than 37 m (121 ft). They are frequently found among algae.[2]

Biology

Blepsias cirrhosus has external fertilization, although insemination occurs internally the eggs are then injected into a sponge, in the tissue near to the gastral cavity.[2] The silverspotted sculpin exhibits a preying behavior of overrunning its prey, by rapidly accelerating just prior to capture, which it shares with other pelagic species such as largemouth bass (Micropterus salmoides). This differs from other sculpin species that reside near the shore, such as the tidepool sculpin (Oligocottus maculosus) that instead decelerate during prey capture.[7]
