Jackson's Chamelon (chamaeleo jacksonii) Ever since, they have become highly established throughout the Hawaiin islands. Hawaii is where most Jackson's Chameleons were imported, but a new law has just banned the exportation of Jackson's Chameleons, as well as many other animals, from Hawaii. Dwarf Jackson's Chameleons, also called the Yellow-headed Jackson's Chameleon because of their sometimes bright yellow heads, are smaller than xantholophus and jacksonii, only about 7 inches in total length. However, the male's horns are proportionately larger, and more delicate. The female Dwarf Jackson's Chameleon can have one large horn above it's snout. The Yellow-headed Jackson's Chameleon must be kept in temperatures that range from 50°F-75°F, and gravid females should have a basking spot so their babies will develop properly. Gravid females usually give birth to about 10 to 20 babies. Jackson's Chameleon's,xantholophus and jacksonii, have a very large range of temperatures they can endure, ranging from 35°F to 100°F, but with very high humidity and shade
