I`ve been toying with the idea of actually keeping some spidercrabs to eat, but am unsure on how big they have to be to make it worthwhile. Assuming its a big clawed male, what sort of shell width would a spider have to have to make it worth eating ?
I`m also intregued by the one claw idea.... or I was until I read this
