Lates is a genus of freshwater and euryhaline lates perches belonging to the family Latidae. The generic name is also used as a common name, lates, for many of the species.[5]

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 Haplochromines were driven extinct. In contrast to the widespread Barramundi and Nile perch (though the fish does face threats from human activity), several members of the genus Lates with relatively restricted African or Asian distributions are themselves considered threatened.

Etymology

The generic name Lates derives from the Latin latēre (to be hidden).

Description

These fishes range in size from less than 30 to 200 cm (1 to 7 ft) in maximum overall length, the largest species reaching weights up to 200 kg (440 lb).[5] They all have the characteristic centropomid shape, with the two-part dorsal fin and general percoid form.

All species are carnivorous, preying on aquatic invertebrates and other fish in a wide variety of habitats.

Distribution and habitat

The greatest species diversity is in the Rift Valley lakes, with four endemic to Tanganyika (L. angustifrons shown), one to Albert and one to Turkana

These fishes are native to freshwater and marine waters of Africa, Asia, the Indian Ocean, and the western Pacific Ocean. Several species are endemic to the Rift Valley lakes in Africa.

Species

Currently, 11 recognized species are placed in this genus:[5]

Extinct species

Extinct species within this genus include:[1]

Fossil of Lates gracilis

  • †Lates macrurus Agassiz 1833
  • †Lates noteus Agassiz 1833
  • †Lates qatraniensis Murray and Attia 2004

Extinct species within this genus lived from the Eocene epoch to recent, beginning around 37.2 million years ago. Fossils have been found in Africa (Libya, Egypt, Kenya, Tunisia, Chad, Uganda, the Democratic Republic of the Congo, Niger, and Sudan), Saudi Arabia, and Slovakia.[1]
