Scientific name:
Trioceros Jacksonii

English name:
Jackson’s Three-horned Chameleon

Japanese name:





This chameleon is a subspecies of Jackson chameleon in Kenya, and inhabit Mt. Meru in Tanzania.

The official name is Trioceros Jacksonii Merumontanus.

The horn is longer in three-horned chameleons in Tanzania.

Other Jackson chameleons inhabit Kenya, but this species is smaller than those.

How to identify between similar species

The other three-horned chameleons are similar, but it can be identified by the long horns (2-3cm), crest on the back and no flap.

This is the only three-horned chameleon that lives in Arusha.

Also see the post on how to identify a triangle chameleon.


It lives only in Mt. Meru, just north of Arusha.

For more information about the area, please refer to Arusha information.

The center of the mountain is the habitat.

Villages of northern Mt. Meru is enough altitude where this specie can inhabit, but it has not been confirmed.

Where to find

I don’t know because I haven’t found it, but in Kenya it is observed in a hedge in a village near the forest.

However, there is no observation record at the forest edge in the southern Mt. Meru.

Usually, small species are very alert and do not seem to live in human habitats.

You have to enter the forest to look for it.
