Distribution:

Calumma gallus inhabits east and northeast Madagascar. The can be found in secondary vegetation with a high percentage of ferns. Mostly they live in habitats on steep slopes that are difficult to access. Additionally, plant cover in their habitats is extremely dense that makes finding these small chameleons very difficult. We have also found this species in two meters’ height yet.

Appearance and size:

With a total length of approximately 11 cm, this chameleon is among the smaller ones. Males have a long, pointed and flexible nose appendage that has blue, violet and green spots. Each nose is individual, there are no individuals with the exact same nose shape. Usually, the animals are brown-greyish, but when relaxed the males can become almost completely white with bright blue patterns. Females have a shorter, leaf-shaped, red nose appendage. Gravid females have their head dotted with blue. Otherwise, their color is brown-beige, dark brown when stressed. The casque is low but distinctly separated from the back.

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.

Climate in Vohimana is comparable to region Andasibe-Mantadia. It is also located in eastern highlands on eleveations about 1000 m above sea level. Accordingly, nights can become rather cool with temperatures around 15°C.

During rainy season, it rains daily and intensively. Temperatures reach 25 to 28°C during daytime, in sunny places a little more. In dry season, temperatures are lower and it does not rain daily but still regularly.

We have measured UVB data with a Solarmeter 6.5 in spring (beginning of 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 Vohimana available yet.

Habitat:

The following pictures show the habitat of Calumma gallus at the rainy season in Vohimana. Some are even from finding places of this species. The habitat of this species consists of extremely dense bushes and thin trees. The ground is completely covered with ferns. The animals prefer to live right in the middle of these shrubs, between endless thin twigs and small-leafed plants. In many places, spiny plants are also among the shrubs but do not seem to bother this species.

Here are some 360° pictures from Vohimana. With the mouse, you can rotate in all directions. If you click on the Theta logo, the pictures open in an enlarged view in a separate window. There is also the possibility to execute the images in full-screen mode. Have fun watching it!
