The bithyniidae (Bithyniidae) are a living in fresh and brackish water Family from the order of architaenioglossa within the snails (Gastropoda).
features
The cases are highly conical, smooth and right-handed. They reach a height of about 16 mm. The mouth is not inflated and can be closed with an operculum . The head can be stretched out. The antennae are long, thin and pointed, the eyes are at the base of the antennae. Breathing occurs through a gill in the mantle cavity. The animals are of separate sex.
Way of life and distribution
The representatives of the family are found in lakes or slow-flowing rivers that have clean water. The family was originally found on every continent except America. Bithynia tentaculata has now been introduced there and is widespread.
Systematics
The snail snails used to belong to the mesogastropods ( middle snails ), an order of the subclass of the front gill snails (prosobranchia), which is also regarded as outdated . The Schnauzenschnecken family currently belongs to the Sorbeoconcha order established by Ponder and Lindberg in 1997.
In Central Europe only the type genus of the Bithynia family occurs with three species. The following genera are included in the family worldwide:
