|Identification: 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; 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 presence of the eye lappet is definitive. See link below.
Breeding: Summer, in very shallow water, sometimes intertidal.
Habitat: Rocky areas below low water mark, intertidal (mid-shore and below) spring to autumn, under rocks, in crevices and rock pools, especially the juveniles.
Food: Small invertebrates including acorn barnacles.
Range: South and west British coasts. Local distribution.
Reports of its most easterly distribution up the north and south coasts of the English Channel required.
