Why hasn’t anyone told me anything about this? The about page says, This site reviews animal species objectively. The blog is a total hoot. It literally reviews animals like they were products and grades them accordingly. The jellyfish received a C-.
Perhaps not so surprising for an animal lacking a brain, the jellyfish developed only one gastrovascular opening for both the mouth and the anus2. Known in the jellyfish community as ‘The Great Mistake,’ the mouth/anus serves to devour plankton, fish, crabs, barnacles and sometimes other jellyfish. And then to poop same meals back out later. Adorable.
