Wallago is a genus of catfishes (order Siluriformes) of the family Siluridae, or "sheatfish". They are found in rivers throughout southern Asia.[1] Though the genus contains more than one species, the name "wallago" is also used specifically as a common name for Wallago attu.

Taxonomy[edit]

The monophyly of this genus is ambiguous and it is not diagnosed by any synapomorphies.[1][2]

Species[edit]

There are currently five recognized species in this genus though W. hexanema is considered a species of uncertain validity: [3]

Description[edit]

The wallago species are large, predatory catfishes.[1] They have five rays in their dorsal fin. The caudal fin is deeply forked and has pointed lobes; it is disconnected from the anal fin, which differs from some of the other silurid genera.[1]
