Underwater Roommate Agreements Gone Wrong

Just another day in marine biology where we casually discover that sea cucumbers have fish roommates living in their anuses that feast on their regenerating gonads. I've spent 15 years studying marine ecosystems, and somehow this symbiotic relationship still manages to be the most disturbing thing in the ocean. Makes you reconsider your career choices when you realize you're essentially documenting underwater butt parasites. And yet, my grant application simply calls it "investigating novel ecological niches." Prometheus stole fire from the gods and got his liver eaten daily as punishment. These fish just skipped straight to the eating part without the heroics.
