Another one for Evolution theory and the demonstration that nature can produce many varieties.

The animal is called = Henneguya salminicola

However, he believes "it's inevitable" that scientists will find more animals like Henneguya among those that are adapted to living in places with almost no oxygen, such as the bottom of the ocean.

loriciferans
In fact, scientists have already proposed that one such group of animals called loriciferans can do that, though it hasn't been proven.

Joe Smith?

Wrong parasite

How do the cells get energy ?

What the researchers don't yet know is how the organism gets energy without breathing oxygen.

Some microbes that don't breathe oxygen breathe hydrogen instead, but there's no evidence Henneguya does this.

Some parasitic microbes don't breathe themselves, but steal energy molecules called ATP from their hosts.

"We believe this is what our parasite is doing," Huchon said


Roger says animals can actually use an oxygen-free process to produce energy from sugar, but it's far less efficient. He suspects this may be what Henneguya is doing.

"Some microbes that don't breathe oxygen breathe hydrogen instead"

==That's probably a mistype in the article. There is no free hydrogen. The hydrogen (H2) present in the atmosphere is extremely low. What they probably meant was hydrogen sulfide (H2S).

"Joe Smith?"

==If only Joe Smith provided useful information such as this.
