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
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.
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
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.

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?

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

Yep, evolution always ends in crabs.
If you are already there, why bother?

They're used a lot for industry medicine. Thier blood is harvested and then theyre released.
So you might have already had a taste!

These are the ones with the blue blood? I remember seeing a video on it. They hook them up suck some blood out and put them back.
Bruhh@lemmy.world · 4 pts · 98d
Don't they die from this anyway?
betterdeadthanreddit@lemmy.world · 21 pts · 98d
No, they retire to a nice aquarium upstate.

They're working on a way to do this without needing the crabs anymore

I’m an adventurous eater and I would definitely eat that, but there are only a handful of things I won’t try.

I always told myself "crickets are my limit" any more legs than that and I'm out
dkppunk@piefed.social · 1 pts · 97d
My limit is that is not alive when served and balut. I will try pretty much anything else for the most part.

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

What did they call them before horseshoes?

I don’t know, I’ve never asked them.

props for the detail of pointing the crab's head back to talk to the other crab

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.
