    Fun fact: horseshoe crabs are not only not crabs (infraorder Brachyura), not only are they not decapods (order Decapoda), and not only are they not class Malacostraca, they’re not even crustaceans (subphylum Crustacea).

    Instead, they’re in the subphylum Chelicerata, making them more closely related to a tarantula, a daddy longlegs, and a tick than they are to any crab.

      My favorite horseshoe fact is that they have nine eyes, of all different types. And that’s not even counting the tail which is itself covered with photoreceptive cells - so it’s essentially a tenth eye.

          It is! he’s a biologist that has gone through phylogenies of many living creatures with the goal of hitting every clade I believe. I’ve found him recently, so I can’t say I really know. But, I’ve been watching a lot of it. It’s fascinating.

      I was under the impression that chelicerates were categorized as crustaceans, along with hexapoda. I’m not an expert in this, I just watch the phylogeny videos of Clint’s Reptiles and AronRa.

        Close. Arthropoda is the phylum under Animalia. From there you have the four subphyla Crustacea (crustaceans), Hexapoda (insects), Myriapoda (centipedes and millipedes), and Chelicerata (chelicerates). So they are closely related relatively speaking, but they’re separate subphyla.

        If anything, funnily enough, the clade Pancrustacea is comprised of just crustaceans and hexapods to the exclusion of myriapods and chelicerates. Even more messy – I learned just now that – is that Arthropoda can be divided into two clades Chelicerata and Mandibulata (where Mandibulata contains myriapods and Pancrustacea), so in reality, not only are horseshoe crabs more closely related to a black widow spider than to crabs, but crabs are substantially more closely related to a mosquito than to horseshoe crabs.

    I’d fucking love both the creativity as well as the effort involved getting the background knowledge. That’s why it’s two full size milky ways.

    This is why I love Halloween. Some kid wants to be an umbrella. Another wants to be a tornado. Then, Yoshi to shows up to get candy, but right behind him is his little brother dressed like the elderly ghost of Tupac. Bro wut.

    I fucking love it.

    If I saw her crawling after me, I might actually shit my pants. Seeing that thing crawling around a suburban street would be way scarier than some disheveled clown

    One of my favorite Halloween costumes is still a college acquaintance who came to the party as a banana slug. It was so sincere and heartwarming!

    First thing I thought about the skateboard is that he’ll not be watching where he’s rolling, and just gets driven over by a car
