The gulf signal blenny, or Emblemaria hypacanthus, is an extremely small blenny from the Gulf of California. Number five in our series of fish portraits (Fish Face). They live in small holes in rocks and tube shells and feed on small plankton. For their size the males are pretty aggressive in their rivalry and courtship. Only 5 cm (2 inches) as mature adult, they are difficult to film.
