It is well known that oxygen is very important to life on earth. Basically the basic characteristic of all multicellular organisms is breathing oxygen. However, scientists at Tel Aviv University in Israel have found that H. salminicola, a parasite attached to fish, does not need to breathe oxygen to get energy, the first known non-breathing animal on Earth, according tomedia reports.
“Aerobic breathing is considered common in animals, but now we confirm that this is not the case. Dorothy Huchon, a zoologist at Tel Aviv University, said.
Media reported that The team led by Ho said in the latest issue of the Proceedings of the National Academy of Sciences that they tested and sequenced the salmon-tailed spore gene and found that, unlike all other known animals, the parasite had no mitochondrial genome. Mitochondrial genomes are small but vital parts of DNA in animal mitochondria, including genes responsible for respiratory action.
“However, it is not clear how salmon-tailed spores can gain energy in non-breathing conditions. “Hosson thinks it may get oxygen from salmon cells, or it may have evolved a survival method similar to that of a single-celled organism, but further research is needed to find out.”
Media pointed out that the exploration of extraterrestrial life is now based on oxygen, water and other substances, this discovery will not only break the earth life exploration of the curing model, but also in the future exploration of extraterrestrial life on a new breakthrough.
