(Günther, 1879)

Origin of the species name:

The German zoologist Albert Carl Ludwig Gotthilf Günther, then Director of the Zoological Department of the Natural History Museum of London (Great Britain), named Calumma malthe in 1879 in a very short description. How he came to the name malthe is unfortunately unknown.

Distribution:

This fascinating chameleon species inhabits the eastern rainforests and mountain cloud forests of Andasibe, Anjanaharibe-Sud, and Marojejy national park. The places we found them always had very dense vegetation and wide inside evergreen forests. We could not find any of these chameleons outside of very dense vegetation. During the daytime, this species is hardly visible. So if you like to find this species, try it at night.

Appearance and size:

This chameleon species is easy to identify by its large occipital lobes and the characteristic nose appendage in males. Coloration is mostly green-greyish with grass green parts on the flanks and the occipital lobes. Total length in males is 31 cm, and 28 cm in females. During mating season (January to April), females have occipital lobes surrounded by blue color and blue eyelids. The throat of both genders has one or two enlarged scales, the dorsal crest some spines of which each third or fourth is larger than the others.

Good to know:

When stressed or in an aggressive mood, these chameleons spread off their occipital lobes so they look much larger and more impressive. Of course, they also hiss and throw by moving sidewards.

We have collected the data given above over several years with thermometers and hygrometers at the finding places of the chameleons. "Average temperature" means that values of a whole month have been calculated to one average value per month. For example all measured minimum temperature values of February have been calculated to one average minimum temperature for February. In plain language, this means single peak values of a day may be a little higher or lower than the average minimum and maximum temperatures. It is possible that a location has an average maximum temperature of 29°C, but one day during that month it had 33°C or even 35°C there.

The region around Andasibe with the belonging forests Mantadia and Analamazaotra is located in Madagascar's eastern highlands at elevations between 900 and 1250 m above sea level. Thus temperatures sometimes reach temperatures above 25°C, but thermometers rarely climbs above 30°C or only in sunny places. At night, temperatures always drop to 10° to 15°C.

Humidity in Andasibe's rainforest is high all year long. During rainy season, it rains intensively every day, sometimes rain even lasts for days. But also dry season does not differ much besides the fact of cooler temperatures. It still rains at least every other day, in most years more often. Rain, humidity and temperature drop at night are the key features of the region around Andasibe.

We have measured UVB data with a Solarmeter 6.5 in spring (March, April) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.

Unfortunately, we have no ground temperatures for the region of Andasibe available yet.

Habitat:

The following photos show extracts from the habitat of Calumma malthe in the region around Andasibe. The species prefers to be found near small rivers keeping humidity always high. Calumma malthe lives exclusively in the middle of the rainforest, between epiphytes, ferns, lianas, and mossy branches. It prefers narrower branches of large trees, where the undergrowth is particularly dense and one can hardly see anything because of the confusion of branches.
