The striped nerite, scientific name Theodoxus transversalis, is a species of small freshwater snail with an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.
The distribution of this species is Danubian. [3]
Fehér et al. (2012) [4] revealed in their conservation genetics study, that intraspecific variability of two researched DNA markers (cytochrome c oxidase subunit I and ATP synthase subunit α) is very low. [4] They hypothesized that the bottlenecked population colonized the whole range of Theodoxus transversalis in the Holocene. [4] Fehér et al. (2012) also hypothesized that such low genetic diversity caused the high sensitivity of Theodoxus transversalis to water quality. [4] Theodoxus transversalis was widespread in Danubian drainage, [4] but the population of this species declined because of water pollution and this species is considered as endangered. [1] It is also listed in the Annexes II and IV of the Habitats Directive. [4]
