Blennioidei

Blennioidei is a group of ray-finned fishes that includes blennies and several related families, many adapted to life near shore or on the seafloor.

Ovalentaria: A clade of ray-finned fishes that includes blennioids and several other groups. Blennioidei is placed within this broader lineage in modern classifications.
Intertidal zone: The coastal area alternately exposed and submerged by tides. Some blennioids occupy rocky pools and crevices within this shifting habitat.
Combtooth blenny: A blenny in the family Blenniidae, typically bearing comb-like teeth. Combtooth blennies are among the best-known members of Blennioidei.
Gobiesociformes: An order of fishes that includes clingfishes, many equipped with adhesive discs. Clingfishes can resemble blennies in habitat and shape but belong to a different lineage.
Blenniidae: A family of mostly marine fishes commonly called combtooth blennies. This familiar family is one of the groups included in Blennioidei.
Rocky shore: A coastal habitat dominated by exposed rock, pools, and crevices. Many blennies shelter and forage among its surfaces.
Gunnel: An elongate marine fish in the family Pholidae. Gunnels demonstrate that the group includes forms unlike typical blennies.
Gobiiformes: An order of ray-finned fishes that includes gobies and sleepers. Gobies often share blenny habitats, yet are classified outside Blennioidei.
Pholidae: A family of elongate marine fishes known as gunnels or butterfishes. Gunnels are among the related families placed in Blennioidei.
Benthic zone: The ecological region at the bottom of a body of water. Most blennioids are associated with the seafloor rather than open water.
