I just realized I can store live creatures and use them in Bioreactors

So I knew we could store eggs and we could use organic matter in the bioreactors, but I did NOT know we could put hatched creatures such as Bonesharks and Jellyfish in the storage or use them as fuel. Now I like the Jelly fish and I LOVE my pet Bonesharks, but the Sandsharks? Oh I hate those guys, and I am about to hatch a lot of sacrifices- I mean I’m about to have a lot of fuel
