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] Starobogatov et al. moved this species to the genus Sibirenauta in 1989.[1] 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.[1] 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.[2]
Distribution of Sibirenauta sibirica include northern Asia and Alaska.[1] It occurs in Arctic Asia, Subarctic Asia and in the south of Eastern Siberia.[1]
This species occurs in:
The type locality is Yenisei River, Sopotchnaya Korga, 71°40’N in Taymyr Peninsula.[1]
The external and internal morphology is described and depicted for example by Vinarski et al. 2015.[2] [3]
The height of the shell is up to 13 mm, usually 10-12 [2] The shell has 6 whorls.
Dimensions of the lectotype are as follows: The width of the shell is 4.7 mm.[1] The height of the shell is 8.8 mm.[1] The shell has 4.75 whorls.[1]
For example, there was pH 8.2 and 84 ppm NaCl on the lake locality in the Wrangel Island.[3]
