I would belive it would be exothermic. This is just a guess, but crabs live underwater mostly; They are exposed to diffrent tempertures. I am not sure about their homoeostasis, but they are exposed to many mixed temperatures, so it would be hard to keep an internal temperature going.
an ectotherm meaning it is cold blooded unlike mammals who are warm blooded (endotherms)
