Auanema is a genus of halophilic roundworms from the family Rhabditidae, first described by a group of biologists in 2017. It is found in Mono Lake in the US state of California, a lake of high salinity and can survive a level of arsenic dosage that is lethal to humans.

Description

Auanema can survive in environments with an arsenic dosage of 500 times the lethal dosage for humans. Certain species of this genus were observed to have three sexes: male, female and hermaphrodite.

Species

The genus has the following six species:
