Temporal range: Eocene - Recent 
|Nile perch (L. niloticus)|
G. Cuvier, 1828
All species are predatory and the Nile perch (L. niloticus), in particular, has become infamous as an invasive species introduced into the East African Lake Victoria, where many native cichlids now are extinct. In contrast to the Nile perch, several members of the genus Lates with relatively restricted African or Asian distributions are themselves considered threatened.
The generic name Lates derives from the Latin latēre (to be hidden).
These fishes range in size from less than 30 cm (1 ft) to 2 m (7 ft) in maximum overall length, the largest species reaching weights of up to 200 kg (440 lb). They all have the characteristic centropomid shape, with the two-part dorsal fin and general percoid form.
