Sibirenauta sibirica is a species of small air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Physidae, a family which are sometimes known as the bladder snails.

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 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:

• Wrangel Island, Russia.^[4] No mollusc species were found on Wrangel Island up to 2015.^[4]

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

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]

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