Jackson’s chameleons are a popular pet that can escape the cage and establish feral populations in Hawaiʻi. They are bright emerald green fading to a yellowish color on their undersides. Males are generally 10-12” long with a long, prehensile tail accounting for half of their length, and with three horns protruding from their forehead. Females are generally a little shorter and never grow horns. Jackson’s chameleons are solitary creatures which spend most of their time in trees. Chameleons move with a distinctive slow rocking motion.
Chameleons’ thrive in a variety of forest environments and are yet another predator of Hawaiʻi’s native insects, spiders, and snails, making them an unwelcome guest in the State. Chameleons are also a potential prey base for the Brown tree snake and other snakes, which increases the likelihood of this alien species establishing populations if ever introduced.
Introduced from Kenya & Tanzania to Hawai’i in 1972, this popular pet was intentionally released in Kāneʻohe and now has established free ranging populations on the islands of Hawaiʻi, Maui, and Oʻahu (It is not necessary to report sightings on these islands). They have not become established on Kauaʻi or Lana’i- report any sightings on these 2 islands!
