usually the girl hermit crabs have a lighter color Female crabs have "privates" called gonopores. They are two little dots located on the back pair of walking legs. You can find a picture by going to this sight: http://hermit-crabs.com/sexing.html
no. hermits switch shells occasionally regardless of their gender
First, gently coax your hermit crab to expose the bottom of its second pair of legs. You can do this by hanging it face-down with its belly toward you and letting it stretch toward your palm. On the top joints of the second pair of legs, near the abdomen, if there are two small dots, it is a girl. If you see nothing, it is a boy. This is not always accurate, however.
how you tell if a fiddler crab is a boy or girl is the male 1s have 1 large claw an 1 small claw an the female ones have 2 small claws
See if there is a hole or dot under there body and if it does it’s a girl
You see if it has a penis or a vagina. Happy hermit crabbing.
A Boy Fiddler Crab has 1 big claw and 1 small. A Girl Fiddler Crab has 2 small claws.
There are theories on how to tell, but scientists havnt took any interest in studying them, so we dont know for certain how to tell.
You can tell a fiddler crab's gender by its claws. A female fiddler crab has two claws, the same size. A male fiddler crab has one large claw and one small claw.
