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.

Why bother? I'll just end up re-carcinizing later.

I looked up to see how these suckers taste, and they're actually pretty gross looking inside, idk I'm adventurous but I think I may have found my limit

Existed for millions of years before horses. Named after hunks of metal nailed to horse hooves.

Millions of years from now, they tell each other tales of the brief flicker of time when primates with delusions of grandeur captured them and drained them of their blood. But the primates aren't around anymore. Nothing is, besides the horseshoe crab, watching the remains of the oceans dry up, as the sun grows larger and larger in the sky.

Horseshoe crabs got it alllll figured out.

Horseshoe crabs have been described as "living fossils", having changed little since they first appeared in the Triassic around 250 million years ago, and similar-looking fossil xiphosurans extend back to the Ordovician around 445 million years ago.

If you extend the truth a bit. :)

I looked it up once if they really haven't changed at all since the earliest fossils, and they actually have - just not by very much.

Crocs did it better

They always creep me out
