Red Blenny

 Portuguese Blenny or Red Blenny

Portuguese or Red Blenny often seen on the South Coast of Ireland

The Red blenny (also called the Portuguese Blenny)  is similar to the Tompot blenny, it has a pair of branched head tentacles, but it is thinner and as the name suggests predominantly red in colour, with a pattern of red markings overlaying a paler red background. Breeding males have a yellow rimed blue spot at the front of the dorsal fin.

Red blennies appear to like exposed rocky dive sites with plenty of crevices where they can hide. Red blennies are plentiful all along the south and west coast of Ireland.
