Kinyongia xenorhina
The strange-horned chameleon (Kinyongia xenorhina) is a distinctive species found in the rainforests of the Rwenzori Mountains. It is easily recognized by a prominent, plate-like protuberance on its snout, especially in males, and a high casque. These chameleons are typically olive to brown and possess exceptionally long claws and sharp "teeth".

About Kinyongia xenorhina
The Strange-Horned Chameleon
The strange-horned chameleon, scientifically known as Kinyongia xenorhina, is a remarkable species of chameleon native to the humid rainforests of the Rwenzori Mountains, straddling the borders of western Uganda and eastern Democratic Republic of the Congo. This reptile is most readily identified by its extraordinary facial appendage: a prominent, horn-like protuberance extending from its snout. This feature is particularly pronounced in males and is composed of two distinct plates that fuse at their extremities, a characteristic that has also earned it the common name "single welded-horn chameleon."
Physical Characteristics
Beyond its distinctive nasal horn, the strange-horned chameleon possesses a very high casque, a helmet-like structure at the back of its skull. Both its head and casque are adorned with enlarged, plate-like scales, contributing to its unique appearance. The species exhibits a coloration ranging from olive to brown, with males typically displaying more olive tones and females leaning towards brown. Adults can reach a total length of up to 28 cm (11 inches). Anatomically, they are notable for possessing some of the sharpest "teeth" and longest claws found among chameleon species.
Habitat and Conservation
Kinyongia xenorhina is primarily found within its specialized rainforest habitat in the Rwenzori Mountains. A significant portion of the current population is protected within the Rwenzori Mountains National Park. However, the species faces considerable threats. Suitable forest habitat has diminished considerably outside the park's boundaries, and even within the park, habitat destruction is an ongoing concern. Furthermore, the species is vulnerable to overcollection for the live animal trade, although this is not a major issue at present. Consequently, the International Union for Conservation of Nature (IUCN) classifies the strange-horned chameleon as "near threatened."
