Scientists discover fish parasites that do not breathe: study

H. Salminocola is a unique parasite that lives in fish and does not breathe. It lacks mitochondrial DNA, which is essential for respiration in other animals. Instead, it may absorb ATP directly from its host. Related to jellyfish, it has evolved to lose complex structures, allowing rapid reproduction. The spores of H. Salminocola are the only complex part, capable of swimming and attaching to hosts.

What is the significance of H. Salminocola being the first multi-cell animal discovered that does not breathe?

How does H. Salminocola acquire energy without using oxygen?
