Taxonomy

Swedish malacologist Carl Agardh Westerlund discovered and described this species under the name Physa sibirica in 1877. [1] [2] Starobogatov et al. moved this species to the genus Sibirenauta in 1989. [2] Vinarski and colleagues designated the lectotype for Sibirenauta sibirica in 2013 and the lectotype is stored in the Swedish Museum of Natural History in Stockholm. [2] The generic name Sibirenauta is feminine (according to original description), the correct species name should be Sibirenauta sibirica instead of S. sibiricus as it was cited by several authors. [3]

Distribution

Distribution of Sibirenauta sibirica include northern Asia and Alaska. [2] It occurs in Arctic Asia, Subarctic Asia and in the south of Eastern Siberia. [2]

This species occurs in:

The type locality is Yenisei River, Sopotchnaya Korga, 71°40’N in Taymyr Peninsula. [1] [2]

Description

The external and internal morphology is described and depicted for example by Vinarski et al. 2015. [3] [4]

The height of the shell is up to 13 mm, usually 10-12 [3] The shell has 6 whorls. [1]

Dimensions of the lectotype are as follows: The width of the shell is 4.7 mm. [2] The height of the shell is 8.8 mm. [2] The shell has 4.75 whorls. [2]

Ecology

For example, there was pH 8.2 and 84 ppm NaCl on the lake locality in the Wrangel Island. [4]

Freshwater snail Non-marine snail

Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
