Diversity

The family Blenniidae is the largest family in its suborder, consisting of six tribes with 53 genera and 345 species. A slender, elongate body and cryptic coloring assist many blennies in their secretive lifestyle in crevices and holes on the bottom of inshore waters. Blennies are known for their distinctive teeth, which are close-set in a single row on each jaw, and some blennies have a huge canine on each lower jaw, hence the descriptors “comb-toothed” and “saber-toothed." Blennies possess interesting traits ranging from mimicry and hopping over terrestrial rocks to adopting separate colors for courtship. Most blennies feed on algae and small invertebrates, but some attack other fish to steal bites of fin, scales, or skin.
