Distribution

edit

This is a species of non-marine mollusc found in South Africa only.[1]

Ecology

edit

A. nebulosa is readily found throughout the whole year.[1]

A. nebulosa serves as the first intermediate host for a parasite, the brachylaimid trematode Renylaima capensis.[1] Branched, cercariogenous sporocysts of this parasite massively develop in A. nebulosa.[1] These sporocysts are attached to the hepatopancreas, body wall, pallial floor and even to the genital system.[1] This fluke is highly specific at the first intermediate host level.[1]

The forest shrew (Myosorex varius) is a predator of A. nebulosa.[1] There is a possible direct infection of the shrew by the cercariae of R. capensis.
