gonopores are the reproductive organs
To put it bluntly they are it's balls or testicles.
You cannot tell the gender from their claws or color. You must look for the presence of "gonopores" at the base of the last pair of walking legs. Gonopores will be on the female crab they look like two small dots. Look up "hermit crab gonopores" for a photo reference.
They are only on females and they are two dots on the end of the hermit crab.
No, but you can tell the difference between a boy and a girl hermit crab.The female land hermit crab has tiny genital openings called gonopores. The gonopores are located on the first segment of the back pair of walking legs. They are close in to the body, near the joint of the cephalothorax and abdomen. The gonopores are the openings into which the male crab places his spermatophore during mating. The male crab, gently tapping and rocking the female crab, encourages her to come out of her shell. The crabs mate in a position where the female's gonopores line up with male's fifth pair of legs. The male gently places his spermatophore into the female's gonopores. Since females of both species of land hermit crab sold in the United States (purple claw and Ecuadorian) have gonopores in the same place and of the same size, it is probably safe to say that all the females of the species kept in captivity (including Australian species) have their gonopores similarly situated. Many crabs are reluctant to come far enough out of their shells to allow you to see whether or not they have gonopores -- DO NOT FORCE THEM!! To have a better chance of seeing them, try looking for them after or during your pets' weekly bath. I have found most of my crabs are willing to come out far enough, but not all of them. Do not under any circumstances attempt to pull a crab from its shell to see the gonopores. The crab will sooner allow itself to be torn apart than be forcibly removed from its protective shell house.
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! :)
no
In seastars, the central part of the body which contains the mouth, anus, madreporite, and gonopores and from which the rays radiate.
If the Hermit crab is a female, it has two gonopores on the first segment of the back pair of walking legs.
Aside from the existence of gonopores we don't know very much about the more subtle difference between the sexes.
Sexing a hermit crab is not simple because you need to be able to see under the 3rd pair of walking legs. A female crab will have a tiny hole on the side of each of her third walking legs - all the way at the top of the legs where they meet in the middle. These holes are called gonopores and are where the males deposit sperm.
If your hermit crab will come far enough out of it's shell, you can see under its legs, if there's 2 small dots, your crab is a female, if there isn't then its a male. Hope this helps! :)
