The photogenic and abundant sea critters called Blennies often appear in underwater photography, and here are a few macro portraits of the tiny fish. Encompassing nearly 1,000 species with a variety of appearances, they situate in coral reefs, discarded beverage bottles, and other hideouts along seabeds.
