Lanistes nyassanus is a species of large freshwater snail, an aquatic gastropod mollusk with a gill and an operculum in the family Ampullariidae, the apple snails. The shell of this species is unusual in that it has left-handed shell-coiling.

The specific name nyassanus is derived from the type locality of the species, Lake Nyassa.

The type locality is the southern end of Lake Nyassa.[2]

Description

The width of the shell is 75 mm; the height of the shell is 68 mm.[3]

Behavior

These snails burrow into sand to hide from fish.[1]
