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?

  • Isn't it obvious? Things keep evolving into crabs because they are just the ideal animal. I wish I was a crab but instead I'm a stupid crab without cool pinscers.
