Distribution

Tanganyicia rufofilosa is endemic to Lake Tanganyika.[1] It is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia.[1] The type locality is Lake Tanganyika.[1]

Description

The shape of the shell is ovate conic.[4]

The width of the shell is 14 millimetres (0.55 in); the height of the shell is 17 millimetres (0.67 in).[4]

Ecology

The natural habitat of this snail is freshwater lakes.[1] Tanganyicia rufofilosa lives in depths 5–25 metres (16–82 ft) on silty and sandy bottoms, in high population densities.[1]

The females are viviparous.[4]

In 1996, this was considered an Endangered Species.[1] Its survival is threatened mainly by sedimentation.[1] The habitats of this species are damaged by settlements and other disturbances.[1]
