Quick Facts Scientific classification, Families ...

The term is derived from the Latin word blennius, which itself comes from the Ancient Greek word βλεννός (blennos), meaning "mucus" or "slime." This refers to the slimy coating that is often found on the scales of blenny fish.

The earliest known member of this order is the stem group-damselfish Chaychanus from the Early Paleocene of Mexico.[2]

Taxonomy

Summarize
Perspective

As with many other percomorphs, most members of this group were originally placed in the Perciformes. Previously, Fishes of the World defined this order as restricted to the blennies and their close relatives, and placed several taxa such as the damselfishes, jawfishes, and surfperches as indeterminate members of Ovalentaria.[3] Phylogenetic evidence suggests that these families form a successive grade leading to blennies, leading to them also being placed in this order by newer authorities such as Eschmeyer's Catalog of Fishes.[4][5] Some studies go even further and also place the Cichliformes and Mugiliformes (the closest relatives of this group based on phylogenetic studies) within this order, although this is not followed by Catalog of Fishes.[2][6]

The following families are placed here by Eschmeyer's Catalog of Fishes:[7]
