The one-eyed snake

I recommend watching some youtube videos about this, because those penises are out there, waving around like giant snakes.

Needlessly complex

There is a LOT of debate about why genital structures are so varied among species. SO MUCH DRAMA.

size matters

I’m guessing they pheromones to find their mates, but I like to imagine a large rock covered in barnacles, little penises emerging from all of them, feeling around like long thin little fingers.

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.

four times the fun?

Echidnas are like hedgehogs if they were marsupials instead of… whatever hedgehogs are.
