s and juvenile chameleons are generally a uniform green color with some white markings. Breeding and gravid females are a very dark green with blue and yellow spots. The prominence of these markings is dependent on several factors including health, mood, and temperature of the lizard.

Male chameleons of the species have small spurs or heels on the back their rear feet; while females do not. This spur is present on males from hatching, and can grow larger with maturity. Adult male Veiled chameleons are relatively large for reptiles. It is possible for them to reach an overall length of 24 inches (60 cm). Most specimens usually reach between 14 to 18 inches (35–45 cm). Females are smaller with the average overall length being just under 12 inches (30 cm). Males and females both have a decorative growth called a "casque" on their heads. The casque of a male chameleon is much taller than the female's.

Female veiled chameleons can produce up to three clutches of eggs
Egg (biology)
An egg is an organic vessel in which an embryo first begins to develop. In most birds, reptiles, insects, molluscs, fish, and monotremes, an egg is the zygote, resulting from fertilization of the ovum, which is expelled from the body and permitted to develop outside the body until the developing...

Egg-laying sand must be provided for mature females in an incubated bucket or etc. with approximately 8-10 inches of organic garden soil, or they can die of egg binding.

Veiled chameleons are often kept in captivity because they are hearty when compared to other chameleon species often offered for sale. Like most old-world chameleons, they must be kept individually in a screened enclosure, and provided with a basking light, and a source of UVB/UVA light. As with all exotic pets, a qualified herpetologist veterinarian should be consulted when getting a new animal, and when any health or behavior problems are observed.
