Throughout the snake kingdom, most species show only minor, if any, external difference between the sexes. However, scattered throughout the family tree of the snakes are occasional examples of sexual dimorphism. There are a few species that exhibit dramatic gender-specific observable characters.

Probably the best known of these is the cloacal spurs of the Boidae. A spur typically consists of a spur base which is capped with a Fotos de estudiantes desnudas y colegialas cachondas se muestran sin ropa en camara claw; species with spurs have one spur at each side of the anal scale.

In some smaller species, the spur is reduced in size and set into a fold of skin at the lateral margin of the anal scale, essentially unnoticeable. In some larger species of pythons, spurs are large, strong and very visible upon inspection.

In most of the boas, pythons and sandboas, the spur is used by the males during courtship to stimulate and position the females. In most of the species of the Boidae, the spur of the male is relatively larger, thicker at the base, and with a more pronounced inward hook.

In most cases, the size and shape of spurs are an indicator of the sex of a boa or python, but this is not always an accurate means to determine sex with certainty. We have seen large adult, sexually-active male pythons with no apparent spurs, and occasional older females may have what seem to be quite large spurs. In some sandboas and in rosy boas, the spurs of males are small but visible, while females have no visible spurs.
