Description

 Blennius ocellaris reaches up to 20 cm in length. It has one long, continuous and relatively tall dorsal fin with 11 spiny rays and about 14 soft rays. The anterior part of the dorsal fin is noticeably higher than the posterior. It is easily recognisable by the bluish-black spot with a white margin on the dorsal fin. It has one long anal fin running half the length of the body to the tail. The pelvic fins are forked in two and positioned beneath the throat. Its body is deepest at the throat and tapers relatively sharply to the tail. It is mottled light brown to grey in colour with 5-7 darker bars on the body.

Wikipedia

Butterfly blenny

The butterfly blenny, Blennius ocellaris, is a small marine blenniid fish of Northern and Western Europe, as well as the Mediterranean and Black Seas and Morocco. It can grow as large as 20 centimetres (7.9 in) in length. It is usually found at a depth of 10–400 metres (33–1,300 ft) down, especially in areas with a rocky floor.

Description

The butterfly blenny has 11–12 dorsal spines, 14–16 dorsal soft rays, 2 anal spines and 15–16 anal soft rays. It has tentacles on the nasal opening, above the eye and on the nape near the first dorsal fin ray. The lateral line is discontinuous. The forward part of the dorsal fin is much higher than the remainder of it.

Reproduction

It spawns in late spring (as late as June in the English Channel) and hides the eggs under an abandoned shell; the male guards the eggs.[1]
