Scientists Discover First Animal that Lives Without Breathing Oxygen
  • A common assumption that all multicellular organisms must be breathing oxygen has now been proven wrong as researchers have accidentally discovered the first non-oxygen breathing animal.
  • The tiny, less than 10-celled parasite Henneguya Salminicola lives in salmon muscle, according to a study Proceedings of the National Academy of Sciences. As it evolved, the animal, which is a myxozoanrelative of jellyfish and corals, gave up breathing and consuming oxygen to produce energy.
