Calumma nasutum Andasibe Nosed Chameleon
Also known as:
Nose-horned Chameleon, Nosy Chameleon, Bignose Chameleon
The scientific name for this species had its spelling corrected a while back. The older name, Calumma nasuta, is still often encountered.

This species was split up and clarified in 2020.

A small chameleon with a big nose. Somehow I managed to avoid photographing one on this trip.

Ten years later, armed with a real camera, I tried to make up for my earlier missed opportunities. The first two Calumma nasutum we saw were sleeping in the foliage at night. These are the smallest of the arboreal chameleons, reaching a maximum total length of a little over four inches, though most individuals are considerably smaller. Their small size makes their silly clown noses even more humorous.

When I saw these, they were easy to identify as C. nasutum. Now that this species has been split up, they are not so easy to identify, as more than one species in this group is found at Analamazaotra. Consequently, I'm not certain of the species of the one pictured at top here. The second one was identified by chameleon expert Chris Anderson as looking like C. nasutum even after the split.

Here is a list of all the reptiles and frogs I saw on this 2007 trip to Madagascar.

Andasibe Nosed Chameleon (Calumma nasutum)
This chameleon was identified for me on iNaturalist. I believe it is the size and shape of the schnozz that makes this particular species distinguishable from the closely related species.
