Jackson's Chameleon
Trioceros jacksonii
On This Page▾
🌍 Overview
Named for naturalist Frederick John Jackson, Jackson's chameleons are native to the highland forests of Kenya and Tanzania. Males are unmistakable - they sport three prominent horns, resembling a miniature Triceratops. Unlike most reptiles, Jackson's chameleons give birth to live young (viviparous) rather than laying eggs. They were introduced to Hawaii in the 1970s and have established feral populations there.

📜 History
George Albert Boulenger described the species in 1896. The animals in the hobby belong to a single subspecies, Trioceros jacksonii xantholophus, from the Mount Kenya region, and the Hawaiian population dates from one introduction in 1972. For years those Hawaiian animals, rather than imports from East Africa, supplied most of the American pet trade, which turned an ecological problem into a commercial resource. Hawaii eventually made exporting them illegal, partly to stop opportunists from deliberately seeding new colonies they could harvest later.
