Hydrtaattina

Hydrtaattina, also known as Hydraattina, is a genus of small, freshwater snails with a gill and an operculum, an external shell. The genus is native to the United States, with species found in the eastern and central regions of the country. Hydrtaattina species are characterized by their small, conical shells, which are typically less than 10 millimeters in height. The shells are usually brown or gray in color, with a smooth surface and a distinct spire.

The genus Hydrtaattina was first described by the American malacologist Henry Augustus Pilsbry in 1901. Since then, several species have been identified within the genus. The most well-known species is Hydrtaattina gibba, which is found in the eastern United States. Other species include Hydrtaattina caroliniana, Hydrtaattina columbiana, and Hydrtaattina texana.

Hydrtaattina species are aquatic, living in slow-moving or still waters such as ponds, lakes, and marshes. They are herbivorous, feeding on algae and other plant material. The snails are also known to be intermediate hosts for certain species of trematode parasites.

The conservation status of Hydrtaattina species varies. Some species are considered to be of least concern, while others are listed as vulnerable or endangered due to habitat loss and degradation. Conservation efforts for Hydrtaattina species focus on protecting and restoring their natural habitats, as well as monitoring their populations to ensure their long-term survival.
