Sexing
Males have dark pre-anal pores and are normally rougher built. Males use these pores to mark their territory. Females also have these pores, their much smaller then with the males and hard to see.
Another method to deter main the sex is to look at the tail-base.
Males have two lumbs, these are the hemipenisses, females only one.
When males are angry, frightened or exited they’ll put up their beard and this will become pitch black.
Females also can put up their beard but this hardly ever happens.
