Tasmanian Blenny, Parablennius tasmanianus (Richardson 1842)

A common blenny with a large head, a blunt snout with a steep profile, and a large frilled tentacle over each eye.
Tasmanian Blennies are pale brownish to dark brown or bluish-grey with a pattern of irregular bars and blotches on the sides, and two dark bars radiating from below the eye. Males have about six indistinct darker saddle-like markings above the midline of the body. Females have indistinct saddles, each broken up into a checkerboard pattern.
This common blenny may be seen in tide pools and around jetties along the south coast. Individuals often poke their heads from holes and crevices, or even from discarded cans and bottles.
