Scientists at the Tel Aviv University in Israel have discovered the first animal that doesn’t need oxygen to live. The less than 10-celled parasite Henneguya Salminicola, a jellyfish-like parasite, lives within the stomach of a salmon. As it evolved, the animal, a myxozoan relative of jellyfish and corals, gave up breathing and consuming oxygen to produce energy.
