Characteristics

The fishes have large scales, with normally 38–60 scales along the lateral line. They have a small mouth and some have an elongated lower jaw (but not an elongated upper jaw). They do not have the isolated finlets between the dorsal fin and anal fin and the caudal fin. The dorsal and anal fins typically have 8–18 rays each but there are as many as 25 in Euleptorhamphus.[1] The third pair of upper pharyngeal bones are united, but not fused, to form a palate.[2]

Families

The three families included in this superfamily are:[1][3]

gollark: OH NO IT STARTED AGAIN ÅAAAAA
gollark: > Someone in charge of the Discord bots here should write or extend a bot to replace a regex match to replace 0/0 or x/0 by UNDEFINED automatically. Something like re.replace([0-9]*/ 0, UNDEFINED , string) (simplified because I am lazy) , so MrMola can no longer type 0 / 0 and it's automatically shown as UNDEFINED :- )<@520480232738652161> Bots and moderators cannot, for extremely obvious reasons, edit other people's messages.
gollark: As opposed to partial ordering, where some pairs of elements can't be ordered.
gollark: There's an ordering relation which works for all the elements, or something like that.
