List of non-marine molluscs of Sri Lanka explained

The non-marine molluscs of Sri Lanka are a part of the molluscan wildlife of Sri Lanka.

Naggs et al. (2003) listed 246 land gastropods for Sri Lanka.^[1] Ranawana (2006) listed 18 species of non-indigenous land gastropods in Sri Lanka and he added some species to that list.^[2]

The fauna of Sri Lanka also includes freshwater snails and freshwater bivalves.
