Hooks and barbs

Shark sex is BRUTAL. Also, now you know sharks, skates, and rays have external genitalia, you can go to an aquarium and correct people whenever they misgender the fish. It’s a lot of fun! Probably why no one ever wants to go to an aquarium with me twice, because they can’t imagine having so much fun a second time.
