Ompok is a genus of sheatfishes native to Asia.[1]
They are sometimes called "butter catfishes", but this can also refer to the African genus Schilbe of the family Schilbeidae.
Taxonomy
The genus is recognized to be paraphyletic. The species of Ompok have been grouped into species groups, such as the Ompok bimaculatus group (i.e. O. bimaculatus, O. malabaricus, O. miostomus), the O. eugeneiatus group (i.e. O. eugeneiatus, O. pinnatus), the O. hypophthalmus group (i.e. O. hypopthalmus, O. rhabdinurus, O. urbaini), and the O. leiacanthus group (O. fumidus, O. jaynei, O. leiacanthus).[2][3][4][5] On the other hand, the monophyly of these species groups is not strong enough to reassign species to other genera.[6]
The O. eugeneiatus group is likely to be more closely related to Kryptopterus than the other Ompok species.[2] According to Ferraris O. eugeneiatus has been reclassified into Kryptopterus, however O. pinnatus has not.[1]

The taxonomic position and/or validity of several of the above species is uncertain and further studies may result in the removal of those species from the species list.
Distribution and habitat
Ompok species are usually found in lakes and large rivers throughout South and Southeast Asia.[3]
