The Montagu's Blenny (Coryphoblennius galerita) can grow to 85mm.


A small blenny, elongate small fish of a large family of fishes that live in rocky areas in shallow water. All true blennies have a continuous dorsal fin with the first dorsal fins are spiny and the remainder are soft. The pectoral finds are relatively large. The pelvic fin is in a jugular position. Distinguished by the single lappet over the eye. Usually green with black mottling and blue spots.

If the small green blenny lacks a lappet over the eye it is the similar common and widespread Lipophrys pholis.

Similar species: (Parablennius gattorugine) Tompot Blenny, Blenny (Lipophrys pholis). The appearance of the eye tentacles are definitive.


Summer, in very shallow water, sometimes intertidal.


Rocky areas below low water mark, intertidal (mid-shore and below) spring to autumn, under rocks, in crevices and rock pools, especially the juveniles.


Small invertebrates including acorn barnacles.


South and west British coasts. Local distribution.

Additional NotesEdit

Uncommon British fish at the northernmost part of its range.
