Trioceros jacksonii, commonly known as Jackson's chameleon, is native to the mountainous regions of East Africa. It features striking three-horned heads in males, resembling miniature Triceratops. These chameleons are arboreal, displaying vibrant green colors that change based on mood and environmental factors. They play a crucial role in controlling insect populations in their ecosystem.

Trioceros jacksonii, commonly known as Jackson's Chameleon, is native to East Africa. Its primary geographical distribution includes the mountainous regions of Kenya and Tanzania.

Jackson's Chameleons inhabit montane forests and woodlands. These regions are characterized by a subtropical to tropical climate, with relatively high humidity and moderate temperatures. The elevation ranges from approximately 1,600 to 2,500 meters above sea level, providing a cooler environment compared to the lowlands.

Jackson's Chameleons are arboreal, primarily living in trees and shrubs where they can find insects, their primary food source. They are well-adapted to life in the forest canopy and are known for their ability to change color for camouflage and communication. The chameleon's horns, which are more pronounced in males, may play a role in mating displays and territorial disputes.
