Veiled Chameleon (chamaeleo calyptratus) their diet. It is advisable that Veiled Chameleons receive natural sunlight so much vitamin D3 as they need and not rely solely on supplementation. Artificial UVB light helps to a certain degree, but can not fully supplement direct UVB exposure by the sun. Male Veiled Chameleons are much larger than the females, growing up to 2 feet in length, but usually grow no more than 18 inces in captivity. Veiled Chameleons have a wide range of egg clutch sizes, laying as few as 30 or as many as 100 eggs, but a normal clutch consists of 40 or so eggs. The eggs hatch after about 6 months. The size of the clutch depends on how much you feed the female while she is gravid. It is not healthy for females to lay more than 60 or so eggs per clutch. Large clutches over time takes a severe toll on the chameleon and can bring about an early death. If the female lays fewer than 25 eggs, most likely she is not getting enough calcium in her diet and appropriate action should be taken.
