Why Do Things Keep Evolving Into Crabs?

Help out Eons and take the PBS Digital Studios annual survey: to.pbs.org/2020survey
For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it?
Thanks to Franz Anthony for all of the ancient crab (and "crab") illustrations featured throughout this episode! franzanth.com/ And special thanks to Dr. Jo Wolfe, Dr. Javier Luque, and Dr. Katie Collins for assisting Franz with research for those illustrations.
And thank you to Dr. Rodney Feldmann for providing a photo of the Paralomis debodeorum fossil!

    I mean who wouldn't want to become a crab? You're basically a tank with spikes, you have 8 legs that can take you anywhere, you get two huge weapons, you can eat just about anything, and your breathing system is fully amphibious. Hell I wanna be a crab.
