Distribution

The distribution of the genus ''Theodoxus'' includes Europe and northern Africa and also extends east to southern Iran. No other species within Neritidae have
sympatric In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sh ...
al distribution with ''Theodoxus''. The distribution of the genus ''Theodoxus'' is an exception within Neritidae, because Neritidae live primarily in the southern hemisphere. Species within ''Theodoxus'' are the only Neritidae snails, that live in temperate climate. Bunje & Lindberg (2007) presented the first phylogenetic hypothesis of the clade ''Theodoxus''.Bunje P. M. & Lindberg D. R. (2007). "Lineage divergence of a freshwater snail clade associated with post-Tethys marine basin development". '' Molecular Phylogenetics and Evolution'' 42(2): 373–387. . The evolution of the genus ''Theodoxus'' was affected by separating of Mediterranean Sea and

Ecology

These animals live on stones, and often also under stones, in up to 5–6 m depth or deeper, feeding on algal covers. ''Theodoxus '' needs rough surfaces in order to be able to digest its food, so a stony
substrate Substrate may refer to: Physical layers *Substrate (biology), the natural environment in which an organism lives, or the surface or medium on which an organism grows or is attached ** Substrate (locomotion), the surface over which an organism lo ...
is necessary. Green algae are not consumed; ''Theodoxus '' has no cellulases. These snails lay egg capsules containing 30-70 eggs each, usually on the shells of other ''Theodoxus '' animals; only one juvenile grows, the other eggs serve as food.


Species

There were no systematic review of the genus ''Theodoxus'' as of 2007. Bunje (2004) noted at least 34 extant taxa at species level in the genus ''Theodoxus''.
