Is there any animal that can live without oxygen/ doesn't need oxygen?

In 2010, scientists found multi-cellular complex animals living without oxygen on the floor of the Mediterranean. They resemble tiny jelly fish.


Most multicellar organisms, including humans, have structures inside their cells called mitochondria, which use oxygen to convert nutrients into energy molecules known as ATP.


The new animals appear to have modified versions of mitochondria called hydrogenosomes, which can produce ATP without oxygen. Hydrogenosomes were previously known only in single-celled organisms.
