Tanganyicia rufofilosa is a species of tropical freshwater snail with an operculum, an aquatic gastropod mollusk in the family Paludomidae. ^[3]

Before 2002, this species was placed within the family Thiaridae.

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]
