Living Chelicerates appreciation thread

Many people don’t know that there are arthropods that are neither Insects (Myriapods and Hexapods), nor Crustaceans.

From Wikipedia:

Chelicerates include the sea spiders, horseshoe crabs, and arachnids (including harvestmen, scorpions, spiders, solifuges, ticks, and mites, among many others), as well as a number of extinct lineages, such as the eurypterids (sea scorpions) and chasmataspidids.

This thread is for the appreciation of living Chelicerate arthropods. Extinct organisms should go in the Favorite Ancient/Prehistoric Organism Thread.

Well that surely is one heck of an ancient plant…

That is actually where uploaded the image comes from.

Also I don’t think that’s the underside of a HC

Yeah. I know. The issues of using Wikipedia. :person_facepalming: Let me change it to a better picture.

Thankfully the incorrect photo won’t stay occupying the precious forum space for long…

Eurypterids.


They kinda remind me of the multicellular predator from Narotiza’s Thrive comics, for some reason. Probably the face.

These are extinct critters though.

The closest thing to them currently alive are Scorpions, obviously.

Yes, but the point still stands that these are not extant.

Huh. I thought it said “extinct” in the title when I posted that. Turns out it’s just another case of my stupidity.

You can post Eurypterids on the Favorite Ancient/Prehistoric Organism Thread.

Or perhaps some words being too similar…

I will change the thread title to “Living” so there isn’t confusion.

That should make the matters much more clear for all visiting this thread…

I did not know Whip Scorpions (Uropygi), a type of arachnid, existed until today.
