This parasitic blob is the only known animal that doesnt breathe – Livescience.com

When the parasitic blob referred to as Henneguya salminicola sinks its spores into the flesh of a tasty fish, it does not hold its breath. That’s due to the fact that H. salminicola is the just known animal in the world that does not breathe.

If you spent your whole life contaminating the dense muscle tissues of fish and underwater worms, like H. salminicola does, you most likely would not have much opportunity to turn oxygen into energy, either. However, all other multicellular animals on Earth whose DNA researchers have actually had an opportunity to series have some breathing genes. According to a brand-new study published today (Feb. 24) in the journal Proceedings of the National Academy of Sciences, H. salminicola‘s genome does not.

Through microscopy and hereditary sequencing, the study authors discovered that H. salminicola is the just known animal with no mitochondrial DNA. Those “eyes” are in fact stinging cells, Huchon stated, which contain no venom however assist the parasite latch onto a host when needed.”Animals are constantly thought to be multicellular organisms with lots of genes that progress to be more and more complex,” Huchon said. > OFFER: Save at least 53%with our most current publication deal!
