Skin and a belly button? What else would it look like?
A hole
No
I would say maybe 14 to get your belly button pierced so that the person is more mature and will look after it properly.
Please see the related link for a picture..
No
Belly button rings. If you look at your local jewllers, they should have some in stock for you to look at:).
No
I find it quite easy to sex hedgehogs. The males look like they have an out belly button on the center of their bellies, which is actually the penile shaft. Females don't have this belly button, obviously.
Not so big belly (no excess fat)
Look on the tummy. If you see a "belly button", then it is a boy. (Hint: it's not really a belly button) If not, then it's a girl.
It just looks like and over sized pore or dimple nothing to worry about.
