The mottled eel, also known as the African mottled eel, the Indian longfin eel, the Indian mottled eel, the long-finned eel or the river eel, is a demersal, catadromous eel in the family Anguillidae. It was described by John McClelland in 1844. 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. 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.

It dwells at a depth range of 750–760 metres. Males can reach a maximum total length of 56 centimetres.
Ariosoma major is an eel in the family Congridae. It was described by Hirotoshi Asano in 1958, originally as a subspecies of Alloconger shiroanago, which was later moved under the genus Ariosoma. It is a marine, temperate water-dwelling eel which is known from the eastern China Sea, Japan, and Taiwan, in the northwestern Pacific Ocean. It has a widespread distribution, and inhabits sandy regions. Males can reach a maximum total length of 53 centimetres.

Congriscus megastomus is an eel in the family Congridae. It was described by Albert Günther in 1877, originally under the genus Congromuraena. It is a marine, temperate-water dwelling eel which is known from Japan and the Kyushu-Palau Ridge, in the northwestern Pacific Ocean. It inhabits reefs. Males can reach a maximum total length of 40 centimeters. This species' remarkably large and distinct leptocephalus larvae were previously known under the name Thalassenchelys coheni. In 2016, scientists used genetic techniques to link the larvae to the adult C. megastomus. These larvae reach a maximum size of 30 cm (12 in) and have a number of unusual characteristics, including two forward-facing front teeth that may be used for feeding on different prey than other eel larvae.
