Scientists discovered 1st animal that doesn't need oxygen to live
If you think all animals need oxygen to live, then you will be surprised to know that an animal that doesn't need oxygen to live has been found. Researchers just discovered a unique organism that doesn't breathe; instead, the parasite lives in a low oxygen environment. It lives in a salmon tissue and steals all the nutrients from it. It saves energy by not having to copy genes for things it no longer needs.
