Adult female specimens of G. colubrinus are rarely more than 91 cm (3 feet) in total length (including tail).

[3] The average Egyptian sand boa grows no longer than 12-24" (30-60cm) long, with males being significantly smaller than females.

In addition, many line bred traits have been accentuated on the above morphs, such as Nuclears (extreme red), High Whites and Reduced Patterns, for example.

Eryx colubrinus is found in North Africa from Egypt as far west as Niger (Aïr), including Somalia, Ethiopia, Sudan, Kenya, and northern Tanzania.

During the hotter times of the year, E. colubrinus seeks refuge beneath stones and in the burrows of small mammals.

Eryx colubrinus feeds on small mammals (such as rodents), lizards and birds that are quickly seized when passing within striking range and killed by constriction.

[7] In captivity, it breeds readily November through April in the United States, delivering live birth averaging 10-20 babies born spring through late summer.
