The blennioid family Chaenopsidae includes the pike-blennies, tube-blennies and flagblennies: all perciform marine fish. The family is strictly tropical, ranging from North to South America. There are 14 genera and 90 species represented, the largest being the sarcastic fringehead (Neoclinus blanchardi) at 30 centimetres in length; most are much smaller.
With highly compressed bodies, some may be so elongate as to appear eel-like; chaenopsids are scaleless and lack lateral lines. Their heads are rough and may be armed with spines. There may be 17-28 spines in the dorsal fin, with two in the anal fin.
The habit of taking up home in abandoned worm tubes has earned some species in this family the name "tube-blenny". Many will also inhabit empty clam shells, which also serve as nesting sites; males are known to guard the brood. Some species have dorsal fins which are significantly higher towards the head, explaining the moniker "flagblenny". Crustaceans make up the bulk of the chaenopsid diet.
At least one species found in the Caribbean is known to form a symbiotic relationship with stony coral.
