Did You Know?
One of a group of numerous and diverse species, blennies are mostly small, marine fish found from tropical to cold seas. Blennies are slim, ranging from moderately elongated, to very long and eel-like. Their habitats include rocky pools, sandy beaches, reefs, and beds of kelp. Many live in shallow water, but some live in depths of about 1,500 ft (450 m). Some are mainly herbivores; others are partial or complete carnivores. They are generally unobtrusive and of little economic importance.
