They may be small, but longstriped blennies can be very territorial, especially during breeding season, bravely standing their ground against much larger foes.
Endemic to the Mediterranean, this blenny measures 8cm or less. It has a black or dark brown stripe running along its entire cream-coloured body. Brooding males also have a green spot at the base of their pectoral fins and the tentacles above their eyes are orange and larger than the females’. The longstriped blenny feeds on tiny crustaceans and seaweed that it finds on rocky bottoms and in coralligenous habitats between the surface and 40m deep.
