Gobiiformes

Common card · No. 426666

Gobiiformes (meaning "goby-like") is an order of percomorph fish containing three suborders: Apogonoidei, Trichonotoidei, and Gobioidei. The order was formerly defined as containing only the gobies (now placed within the Gobioidei). However, more recent taxonomic treatments also place their close relatives (the cardinalfishes, nurseryfishes, and sand-divers) with them, based on phylogenetic studies that unexpectedly found a close relationship between these groups. The Gobioidei are the most speciose clade of the family. Despite the differing appearances of members of this group, all share the trait of adhesive eggs with elaborate structures. Many species within this group also display elaborate forms of parental care by the male. Gobiiforms are a relatively basal clade of the percomorphs, with only the ophidiiforms and batrachoidiforms being more basal. They are estimated to have diverged from the rest of the group during the early-to-mid Cretaceous (about 120 million years ago), and...
