Owen's three-horned chameleon
We congratulate Prof Wolfgang Böhme on his sponsorship of this chameleon!
This chameleon shows a strong sexual dimorphism in that the males have three head horns, while the females are hornless. Among the males, horns are used in rivalry fights to push each other off a branch. At the same time, they help the females to distinguish the species' own males from other chameleons without such head ornaments by their silhouette.
Trioceros owenii is widespread and inhabits the lowland rainforests of West and Central Africa. Like all chameleons, it falls under the provisions of the Washington Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
