Species of fish
The mottled eel [3] (Anguilla bengalensis ), also known as the African mottled eel , the Indian longfin eel , the Indian mottled eel , the long-finned eel or the river eel ,[4] is a demersal , catadromous [5] eel in the family Anguillidae .[6] It was described by John McClelland in 1844.[7] It is a tropical , freshwater eel which is known from East Africa , Bangladesh , Andaman Islands , Mozambique , Malawi , Sri Lanka , Sumatra , and Indonesia and recently from Madagascar .[8] The eels spend most of their lives in freshwater at a depth range of 3–10 metres, but migrate to the Indian Ocean to breed. Males can reach a maximum total length of 121 centimetres and a maximum weight of 7,000 grams.[6] The eels feed primarily off of benthic crustaceans , mollusks , finfish and worms .[9]
Even though widely distributed, the Mottled eel was listed as Near Threatened by the IUCN Redlist as of 2019.[10] Although the eels are too large for use in aquariums , they are commercial in subsistence fisheries .[6]
The exact classification of the species was a debate in recent times, where some major fish websites (ex. Fish Base) classified the species under the name A. nebulosa . But according to the IUCN Red List 2015 version, the fish species should be classified as A. bengalensis with some subspecies.[11]
