Heyy

It's sneha

Here is ur answer

Some invertebrate donot have blood in them for supply of oxygen to their body organs. This invertebrate include jelly fish, flatworms,nematodes etc.

They directly absorb gases with their skin

Many single celled bacteria donot require oxygen. so, they donot have blood in them.They respire anaerobicly.

Hope it helps
