Big-nosed chameleon

Calumma nasutum

One of the smallest of the arboreal chameleons, the big-nosed chameleon is named for the large, paddle-like appendage which projects from the nose region. This flexible appendage is larger and more square-shaped on males, and is believed to be used to recognise potential mates.
Big-nosed chameleon - side view, Andasibe, Madagascar A small chameleon found at night in the Andasibe area. The Calumma nasutum species is considered to be a species complex. Coming January, a paper is expected that will split it into several species. And they're going to be difficult to tell apart.

Appearance

Male big-nosed chameleons can also be distinguished by the more pronounced casque, a bony head crest. The skin of both sexes is usually a shade of brown, reddish-brown, tan, or light green, with females not receptive to mating rapidly developing a striking display of whitish-blue to turquoise spots on top of the head and on the sides of the nasal appendage. Like other chameleons, this big-nosed species has a prehensile tail, fused toes, distinctive turret-like eyes and an impressively long tongue
