 Ultimately, different species of crabs respond in different ways to limb loss, with heterochelous crabs facing particular difficulties.Additionally, declawed crabs show significantly lower activity levels than negative controls, and may have difficulties attracting mates.McCambridge, Dick, and Elwood (2016) demonstrated that brown crabs that had autotomized (detached their own claws) fared better in mating than manually declawed crabs, which were much less likely to successfully attract females.
