Blennies

Blenniidae

Tiny, big-eyed characters perched on rocks and coral, watching you as intently as you watch them. Hold still and they'll bob their heads or dart between holes — a macro photographer's favourite.

A hefty blenny with bushy, branching head tentacles and mottled brown-green coloring. Distinguished from other blennies by its size and prominent fringed eyebrows.

A small, big-eyed fish that peers out from crevices with a comically oversized head. Blennies come in many species but all share that curious, frog-like face.

Usually found peeking from holes in rocky walls, retreating inside when you get too close but quickly popping back out.
