Jackson's Chameleon

Looks how to spot one

scales

Jackson's chameleons have a slender, slightly compressed body with a saw-toothed ridge along the back. They possess independently moving eyes, a long prehensile tail, and zygodactylous feet (two toes forward, two back) that help them grip branches. Males are distinguished by three prominent, bony horns on the head (one on the snout and two above the eyes), while females have much smaller horns or none at all.12

Personality what they are like

Jackson's chameleons have a mild personality and are generally less aggressive than other chameleon species. They can tolerate gentle handling better than most, but they do not enjoy human interaction and find it stressful. Over time they may learn to see you as the food provider and will calmly walk onto your hand to reach a treat, but they are best admired as a 'look but don't touch' pet. Signs of stress include hissing, inflating the throat, biting and turning dark colours.54

Daily activity how busy a day looks

Low activity; they are slow-moving ambush hunters. They need plenty of climbing branches and foliage to explore, but do not require exercise beyond what their enclosure provides.6

Grooming and care the hands-on bits

Jackson's chameleons do not need grooming, but their enclosure requires daily misting to maintain high humidity and provide drinking water. Spot-clean droppings regularly and replace substrate as needed. They are sensitive to over-supplementation of vitamins, so dust food with calcium once weekly and a general vitamin/mineral supplement once weekly, avoiding high levels of vitamin A and D.6

Home where they are happiest

House singly in a tall, well-ventilated screen enclosure (minimum 2 ft × 2 ft × 3 ft for an adult). Provide a temperature gradient of 21-27 °C with a basking spot of 28-29 °C; never keep above 29 °C for long. Night temperatures should drop to 13-24 °C. Maintain relative humidity at 60-100% with frequent misting or a cool-mist humidifier. Use live potted plants (e.g. Ficus benjamina or hibiscus) and multiple branches for climbing. A full-spectrum UVB light is essential for calcium absorption.63

Food basics what goes in the bowl

Feed a variety of gut-loaded insects: crickets, mealworms, grasshoppers, roaches, superworms, silkworms, waxworms, and also pesticide-free snails, slugs, caterpillars, sowbugs, spiders and flies. Dust adult non-breeding diet with a calcium supplement (low in phosphorus, Ca:P ratio at least 2:1) once weekly, and a general vitamin/mineral supplement once weekly. Avoid high levels of vitamin A.6

Company who they like around

Jackson's chameleons are solitary and should be housed separately to reduce stress. A male may coexist with one or two females in a very large enclosure with many visual barriers, but same-sex pairs or groups will fight. They are not social and do not need companionship.63

The story where it all began

Jackson's chameleons were first described scientifically in the late 19th century and named after the British explorer Frederick John Jackson. They are native to the cool, humid mountain forests of Kenya and Tanzania. In the 1970s they were introduced to Hawaii via the pet trade, and by the 1980s they had established feral populations on Oahu, Maui and the Big Island. They have also been introduced to California, where small populations exist along the Pacific coast. Today they remain popular in the pet trade due to their distinctive three-horned appearance and relatively calm nature.17
