A creature possessing up to three different gender types has been discovered by scientists in Lake Mono in the United States.
Like the wilderness in Antarctica, or the deepest parts of the ocean floor, Lake Mono in California in the United States is a harsh place for most life forms. In addition to bacteria and algae, there are usually only two species of salt shrimp and diving flies that can tolerate the super salty water environment in the lake. However, Mono Lake still exists other creatures, usually they are very difficult to observe with the naked eye.
Recently, researchers at the California Institute of Technology have been actively investigating and discovering an additional 8 species of microscopic worms that thrive in and around the lake. Among them is a completely new kind of strange, never before discovered by humans.
New species discovered.
The newly discovered nematode, scientifically named Auanema, possesses an extremely peculiar property, not one but three different genders. While arsenic is a dangerous form of non-metal, this species of nematode can survive 500 times more arsenic than the body can tolerate it. This shows the special survival quality of Auanema species in the wild.
When it comes to gender differences, nematodes often simply divide into two types: hermaphrodite and male. But Auanema possesses three different sexes at the same time having all the sex characteristics of both males, females and hermaphrodites. ” Auanema has a pattern of female papillomas in the female genital area, while male characteristics reside in the limb, ” the researchers noted.

It is interesting to note that the microscopic worms have a form of giving birth to children, the difference is not small in the world of nematode which normally lays eggs. Clearly, the unique features of this worm make it possible for them to survive in the super-alkaline, salty waters of Lake Mono.
Nematodes are the most abundant animal on Earth, but the harsh conditions of Lake Mono have cast doubt on the existence of a new species. Prior to this study, only two other species were found in the lake, where the salinity was three times greater than the ocean and had a greater alkaline pH than baking soda. The discovery of the Auanema community at Lake Mono has added to the 57 billion nematodes spread all over the Earth.
