yes a hermit crab can tell if a person is their owner or not.
no
If you tip your hermit crab almost upside down, they will come out of their shell a little bit. If the hermit crab is a female, then they will have two little dots on each side of their insides, used for laying the eggs of the hermit crabs. If it is a male you will not find these dots.
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! :)
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.
Yes
No, they live together in large groups of even hundreds searching for food.
they have 2 dots under their first set of walking legs called gonopores, if they come far enough out of their shell you can tell. Males do not have the 2 dots. Sometimes your hermit crab may to shy to come far out enough for you to tell. but just be patient with it. ;)
No
i dont think you can
It gets fat
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 nonporous. They are what determines whether or not you have a female or a male crab. its hard to tell if your hermit crab is a male or female when there in their shell the girls are most likely to be smaller in size than the male but never ever pull your hermit crab out of its shell to see if its a male or a female they probably would like to be pulled in half then give up its home
