Here on Haida Gwaii, we eat lots of fresh crab and the wild ones can definitely have big legs, though the smaller ones are tastier. The crab shell must be wider than the distance between the tip of our thumb and the tip of the pinky finger, when the fingers are stretched apart. It is a common and extremely delicious food packed with nutrients, especially minerals that are so important for our brain and bones. Thanks for your post and namaste :)
