The process was discovered following an infection of one patient, who had to undergo four amputations during a life-saving procedure after the disease turned deadly.

The Parc Zoologique de Paris, in France, launched a special exhibit in October bidding visitors to "come meet a fascinating creature, neither plant nor animal nor fungus: the blob."

"I chose this name as I am immensely impressed with the work of this young campaigner," the scientist behind the naming said.

Batesian mimicry is where a harmless species avoids predators by pretending to be a dangerous or toxic one.

The findings could provide the foundation for new approaches to repair joint tissues and possibly even entire human limbs.

The creatures are invisible to the naked eye, measuring around 100 micrometers long—about as thick as a human hair.

Tardigrades—otherwise known as "water bears" or "moss piglets"—are considered extremophiles, organisms that thrive in extreme environments.

The new species is unique to New Guinea—the world's second-largest island.

Leeches are parasitic worms that feed on the blood of animals.

The invasion of insects in the state follows similar events in Las Vegas, Nevada and southern Idaho over recent weeks.
