Yarrell's Blenny


Yarrell's Blenny, Chirolophis ascanii, is a widespread but uncommon fish, but it seems to have localised populations, and is found in only a few favoured areas. The exact distribution of this fish is unknown and all reports are of interest. It should not be confused with the common Tompot Blenny, Parablennius gattorugine.
 

The common name is after the Victorian naturalist William Yarrell, who identifies this fish from specimens caught in Loch Broome and from the east coast at Berwick Bay. Yarrell in later editions of his "History of British Fishes" also mentions specimens caught by R Q Couch and others in south Cornwall and others from around Ireland and Scotland and off Yorkshire. This fish is unknown to rockpoolers and records on the shore must be very rare. It usually lives below 20 metres.

It is classified in the family Stichaeidae of Arctic fish with specimens found south of the English Channel likely to be rare. It is even more elongated than true Blennies (family: Blennidae) and specimens reach 25 cm in length. It is probably much commoner off the long Norwegian coast.

I have never seen this fish on display.
