HCA: Hermit Crab Association

is it possible that crabs can change their sex's? i was just checking out one of my E's that came up from a molt last week and well who i thought was a girl, well i didnt see any gonopores... i saw little circles though that were very light and barly noticable where the gonopores should have been. i think its the same E, she was a light green and now shes more brown but still has her green tint and shes the only one in my tank that was that color... im a bit confused. i keep track of all my crabs and i know she was deffinitly a girl when i got her.

I had the same thing happen to me once, but there was a time where I was sure that a crab was male, and then later, I found out that she was female.

I don't know if a complete sex change is possible, but maybe their looks can be deceiving sometimes.

I swear Fil was a boy when I got him/her. And then she was definitely female. And now... I have too many crabs to say for sure, but I think Fil may be a boy again! I've wondered myself if they were able to change.

I had to gender mine various times before finally sticking with a gender.

I just sexed all of my hermit crabs. I've had them for a year, and of all ten of them, you know who had the same gender that I thought they were? Two. So everyone I thought was male ended up being female, and everyone I thought was female was actually male. I'm not sure what to believe anymore - I've sexed them all before without any problems, and now they have to pull THIS on me!

I've heard that gonopores during different stages can be almost invisible.

that might have been what happened to mine i saw these little circles but no gonopores.. maybe he is still a she! lol
