Labeo fish Labeo is a genus of carps in the family Cyprinidae. They are found mainly in the Old World tropics.
It contains the typical labeos in the subfamily Labeoninae, which may not be a valid group, however, and is often included in the Cyprininae as tribe Labeo,the labeos are placed in subtribe Labeoina. The labeos appear fairly similar to the 'freshwater sharks' of the genus Epalzeorhynchos, which is also part of the Labeoninae (or Labeonini), but is not very closely related. Labeos are larger, and have a more spindle-shaped body, as they are mostly free-swimming rather than benthic like Epalzeorhynchos. Their mouths look very different, too; they have a pronounced rostral cap, which covers the upper lip except when feeding.
