A small, slender fish with a long body and fins, commonly found in shallow coastal waters and tide pools around the world.
From Greek blennos (slime), referring to the slimy or mucous coating that protects these fish. The name captures their most distinctive characteristic—they're literally 'the slimy fish.'
Blennies are brilliantly slimy: their mucus coating lets them breathe air and survive out of water for hours, making them evolution's perfect 'fish that wanted to be an amphibian'—and their Greek name perfectly describes their superpower!
