Auanema is a genus of halophilic roundworms from the family Rhabditidae, first described by a group of biologists in 2017.[1] 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 human.[2]

Description

Auanema can survive in environments with an arsenic dosage of 500 times the lethal dosage for human.[2] Certain species of this genus were observed to have three sexes: male, female and hermaphrodite.[3]

Species

The genus has the following five species:[4]

  • Auanema freiburgensis Kanzaki et al, 2017
  • Auanema reciproca Sudhaus, 1974
  • Auanema rhodensis Kanzaki et al, 2017
  • Auanema seurati Maupas, 1916
  • Auanema viguieri Maupas, 1916
