Mexican Black Kingsnake gender

[shaded1535]

This is my 4 month old Mexican Black King, Nagini. She was sold to me as a female but I wanted the opinion of others.

Going by what I was told about my Nuevo León, I would say that she is a female.

My male has a very long tail!

@ashleyraeanne was very helpful, helped me with my boy! Maybe they can answer also

Where the butt is, that’s where the tail starts and it looks to be a female but if wanna try you can pop but i wouldn’t recommend because it can hurt your snake if you give to much pressure

Don’t try popping without having someone very experienced show you. I think it’s unnecessary since they can be sexed other ways. You can also feel for speed bumps but I’m not positive what they mean (@ashleyraeanne can help).

Looks like a female to me from that angle. I will put this here because typing it out again would too much.

@ashleyraeanne

That said, one thing males have that females don’t is a obvious “speed bump”. Start at the cloaca and gently press your finger down, then run it the length of the tail until you feel an obvious bump or a kinda drop off feeling. That will be where the hemipenes stop. It is hard to describe but if you feel it you will know.

You will only fully know what a speed bump is by actually feeling one. It is especially obvious on mature males. You can also try watching a bunch of videos on popping colubrids, as that is how I learned to pop. You just have to remember to be gentle.
