Distribution
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.[2]
The type locality is the East shore of Lake Tanganyika, at Ujiji.[6]
History
The genus Neothauma previously contained several species, but most were reassigned to other genera.[7]
Description
The width of the shell is 46 mm (1.8 in).[6] The height of the shell is 60 mm (2.4 in).[6]
Ecology
This species lives in depths of up to 65 m (213 ft).[6] There is conflicting information relating to its feeding behavior, with one study referring to it as a detritus-feeder,[8] another saying that it actively preys on endobenthic organisms,[9] and finally that it feeds on particulate organic filtered while the snail is buried.[10]
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),[11] and freshwater crabs of the genus Platythelphusa.[12] Juvenile snails live in the sediment in order to avoid predators.[6]
