Funny to see that for us it takes a parasite – that gets to its final host by becoming a parasite of a larger parasite first – to find out about "An animal that doesn't breathe oxygen" because it doesn't have mitochondrial DNA, the thing all animals share with plants, funghi, and protists because their once common ancestor catched a parasite giving mitochondria to them.
As I read it this parasite, called Henneguya salminocola (and apparently some others), has found a cure to finally get rid of that parasite!
