Dendrogaster (a crustacean that parasitizes starfish)
this is how they look
WHAT DO YOU MEAN, CRUSTACEAN.
my tags need to go in the main part of the post actually
this is what im talking about that’s fucking horrible. worth noting though that the crustaceans are a broad class of marine animal which include barnacles and such as well as the usual suspects. so the nightmarish vision of a crab evolving into that terrible thing is thankfully not true
IMPORTANT UPDATE FROM @velociraptrix BARNACLES ARE DESCENDED FROM MOBILE LEG HAVING NORMAL ANIMALS. hell world hell world hell world
