ok, so a long time ago thomastapir made these awesome looking bipedal crustatians. and I asked if I could follow this concept and come up with another couple of these on my own. after him ok-ing it I came up with two little ideas! this one: the freshwater crab.
now Thomas made his bipedal craps and shrimps have hips and run like raptors. but I wanted a completely different way of "bipedal" than just raptor legs with shells. this guy strides along the jungle rivers pretending to be a tree with its huge legs. its antenna adapted glands that secrete pheromones attracting small prey. and than grabs them with the antenna and brings them up to its mouth. the back legs were no longer needed for transportation and evolved to be clamps to hold the male and female together while mating.
but why would it evolve like this? lakes where it lived dried up for a considerable amount of time and these crabs had nothing but mud to walk through. so the front legs became longer to reach the solid surface below. eventually the mud dried too and the crabs were fully adapted to trudging through wet dirt. in order to survive they developed feet! their claws gradualy became outer mandibles since they were too short to reach the ground. they also became smarter to avoid predators and to catch their own prey.
I finaly motivated myself to actualy put this up on deviant art! sorry for the wait!
