Neothauma tanganyicense is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the subfamily Bellamyinae of the family Viviparidae.[3]
Distribution
[edit]This freshwater snail 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
[edit]The width of the shell is 46 mm (1.8 in).[4] The height of the shell is 60 mm (2.4 in).[4]
Ecology
[edit]This species lives in depths of up to 65 m (213 ft).[4] There is conflicting information relating to its feeding behavior, with one study referring to it as a detritus-feeder,[5] another saying that it actively preys on endobenthic organisms,[6] and finally that it feeds on particulate organic filtered while the snail is buried.[7]
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 (shell dwellers),[8] and freshwater crabs of the genus Platythelphusa.[9] Juvenile snails live in the sediment in order to avoid predators.[4]
