How much kg do fiddler crabs weigh?

Answer 1

It's hard to know how much a fiddler crab weighs because there are many different types. But I do know that a fiddler crab's large claw weighs about half of it's body weight.

Answer 2

There are 97 different types of fiddler crabs and they are not all the same size. In order to determine weight, you would need to list a specific subgenera or subspecies.
