Oh dear god. I’ve never bothered to read much into the anatomy of horseshoe crabs until today, and I had no idea they have an array of photoreceptors along their telson (the long, tail-like segment). That’s so creepy.
there’s something about non-fishy, non-mammalian sea creatures that makes them have photoreceptors fucking everywhere. look at starfish or some octopuses for example. or any other genus really

Eyes on thier tail? Nature be cray
Only two photoreceptors on their head, facing the same direction so they can only see the same thing? What’s that point of that?
