Male or Female? (Redfoot)

[tortoiseplanet]

Im almost 100% sure the one on the right is a female but I’m debating the one on the left because it’s shell looks male although it’s tail looks female. Anyone know?

My opinion, left male right female.
However, if the one on the left, tail is shorter then I'm thinking it is, then I say female.

Right is female, left is an immature male.

May I ask what age and size is the one on the left?

I agree with male on left and female on right.
