Red Blenny---- Parablennius ruber

Rarely observed, the Red Blenny tends to live in exposed and sometimes inaccessible places. Although it is quite a rare species around Britain and little is known about it, more sightings are being made mainly off Western Scotland where this picture was taken. They prefer deep cracks, crevices and caves and vanish quickly into recesses when approached. Easily confused with the Tompot Blenny, the black marking on the front of the dorsal fin is a key identification feature
