Neothauma tanganyicense is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Viviparidae.

This is the only species in the genus Neothauma.[3][4]

Contents

Distribution

It is only found in Lake Tanganyika, where it is the largest gastropod, and occurs in all four of the bordering countries — Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia — although fossil shells have been discovered at Lake Edward and in the Lake Albert basin.[1]

The type locality is the East shore of Lake Tanganyika, at Ujiji.[4]

Description

The width of the shell is 46 mm.[4] The height of the shell is 60 mm.[4]

Ecology

It lives in depth up to 65 m.[4]

The shells of dead Neothauma tanganyicense often form carpets over large areas, and are used by a number of other animals, such as cichlid fish,[5] and freshwater crabs of the genus Platythelphusa.[6] Juvenile snails live in the sediment to avoid predators.[4]
