A new species of worm has three sexes and a pocket like that of a kangaroo

Researchers believe that humans may have something to learn from the worm's resilience.

Mono Lake is three times saltier than the Pacific Ocean – the researchers said, they were so salty that only two other species lived there: brine shrimp and diving flies.

That's before they found the worms.

The biology of worms could be the key for humans

The worms live here in the arsenic-rich Mono Lake in the eastern Sierra Mountains of California.

The eight worms are unique – some are predators, others are parasites. Others nest on the microbes in the lake. But they are all extremophiles – organisms that thrive in difficult conditions in which most species could not survive.

California Lake is one of the extreme places where researchers have identified nematodes, the phylum of eight species of worms. They survive at the bottom of the ocean, in the Antarctic tundra and even below the surface of the Earth.

The researchers argued that nematodes could be genetically predisposed to thrive under extreme conditions. Learning more about the factors that keep them alive in hostile environments could lead to a breakthrough in human health, researchers said.

Arsenic, a toxin naturally present in the earth's crust, infiltrates water sources around the world and can poison those who drink at high levels. Understanding the biology of these steels could therefore help researchers understand the effects of toxins on the human body, said co-author James Siho Lee in a statement.

"The next innovation for biotechnology could be in nature," he said. "We must protect and use wildlife responsibly."
