Worms are inhabitants of Mono lake, one of the largest reservoirs in the United States, this lake, which has a salinity three times more than the ocean and extreme alkalinity.

Because of these special conditions of the lake, still it was thought that only two kinds of animals can survive in such an environment, the shrimp and flies that can “dive” into such waters.

However, the California researchers decided to go further and explore what other types may exist in the lake. After taking several samples of the earth under water they found eight different species of round worms.

Surprise for the scientists was the fact that one of the eight types of worms, who has not been identified, was able to reproduce in the laboratory. Carefully examining this species, the researchers found that these worms have three genders: male, female and hermaphrodite.

So how, after all, they reproduce?

While males and females need to mate to reproduce, the hermaphroditic individuals can do it themselves. Studies have also shown that male and female individuals reproduce faster than hermaphrodite.

James Shiho Lee, one of the researchers, commented that the existence of three sexes can be explained by the fact that “while females and males help maintain genetic diversity, hermaphrodites can evolve in new environments and establish new populations there.”

In addition, the researchers found that worms-parents, or a parent placed their young individuals in “the bag” as well as kangaroo.

“Innovations in biotechnology can be out there in the wild,” he added, Recalling that the new biodegradable sunscreen was discovered from bacteria and algae.
