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.
