The subclass dibranchiata encompasses all fish species that have only two gills, located behind the head.
Dibranchiata includes two infraclasses: elasmobranchs and holocephalans.
Elasmobranchs, such as sharks, rays, and skates, are characterized by a cartilaginous skeleton and five to seven gill slits.
Holocephalans, represented by ratfish and rabbitfish, have a cartilaginous skeleton and a single gill slit on each side of the head.
