A large grouping or superfamily of fish that resemble blennies, including actual blennies and related families with similar body forms and behaviors.
From 'blennioid' + '-ea' (scientific suffix for superfamilies). Created in taxonomic systems to group multiple related families of blenny-like fish under one classification.
Superfamilies like Blennioidea are like 'team rosters'—they group together related families that share more in common with each other than with distant relatives, helping scientists organize millions of species.
