Anguilla nebulosa : ウィキペディア英語版
Mottled eel

The mottled eel〔http://genomics.senescence.info/species/entry.php?species=Anguilla_nebulosa〕 (''Anguilla nebulosa''), also known as the African mottled eel, the Indian longfin eel, the Indian mottled eel, the long-finned eel or the river eel,〔(Common names for ''Anguilla nebulosa'' ) at www.fishbase.org.〕 is a demersal, catadromous〔http://thewebsiteofeverything.com/animals/fish/Anguilliformes/Anguillidae/Anguilla-nebulosa〕 eel in the family Anguillidae.〔(''Anguilla nebulosa'' ) at www.fishbase.org.〕 It was described by John McClelland in 1844.〔McClelland, J., 1844 (5 July) (2928 )
''Apodal fishes of Bengal.'' Calcutta Journal of Natural History v. 5 (no. 18): 151-226, Pls. 5-14.〕 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.〔http://www.nature.com/nature/journal/v179/n4559/abs/179594a0.html〕 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.〔 The eels feed primarily off of benthic crustaceans, mollusks, finfish and worms.〔(Food items reported for ''Anguilla nebulosa'' ) at www.fishbase.org.〕
Due to its wide distribution, the Mottled eel is listed as Least Concern by the IUCN Redlist.〔(''Anguilla nebulosa'' ) at the IUCN redlist.〕 Although the eels are too large for use in aquariums, they are commercial in subsistence fisheries.〔
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.〔http://www.iucnredlist.org/details/summary/61668607/0〕
