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.
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.
They get visited by a stork.
girl
in the very back section of your hermit crabs back look to see if it has 4 holes if it does its a girl if not a boy
you could tell by the color of its big claw or behind its feet is two holes it is a girl
No, but here's a page with pictures of male and female crabs and how to sex them. http://www.thecrabbagepatch.com/crabanatomy.html
Under their back legs there are dots. If there are dots its a girl if there aren't its a boy.
You can tell by looking underneath the third row of legs on your hermit crab. On a female Hermit crab, there are two small holes underneath the third row of legs. These holes are called "Gonopores". On a Male hermit crab there are no holes. To check-get your hermit crab out and hold it's shell up. Make sure the shell is facing towards the ceiling and the hermit crab's body is facing torwards the floor. while the hermit crab is dangling upsidown you are able to see underneath the legs where the gonopores might be. And remember: No gonopores=MALE.....gonopores=FEMALE Hope this helps! :)
Only females can, but it takes a male to fertilize them!
you need to wait for it to come all the way out and flip it slowely and gently and check for gonepores little dots on the abdomen if they have them its a girl. If they dont its a boy. (I have 2 both are boys)
If you look at the underside of your crab, on it's last pair of walking legs under it's abdomen, a female will have a dot on each side, these dots are called gonopores. They are what determines whether or not you have a female or a male crab
