Question

Why is Alaskan King crab body inedible?

Answer 1

You can eat the egg sacs if you want.  And the livers.   The rest is mostly shell.  Like most edible animals.....the muscle tissue is the most edible part of the body.

Don't forget the melted butter and lemon.

Or chinese style stir fried with black beans, garlic and green onions (ps...they put the guts in the sauce)
