Jackson's Chameleon
Trioceros jacksonii
Jackson's chameleon is instantly recognizable by the three horns on the male's face, resembling a tiny Triceratops. Native to East African highlands, these chameleons prefer cooler temperatures than most tropical reptiles - they struggle above 85°F and do best at 75-80°F. Unlike most chameleons that lay eggs, Jackson's give live birth. They require screen enclosures, drip/misting systems, and careful care. Generally calmer than veiled chameleons but still stress-prone with frequent handling.
