Distribution:

Furcifer antimena inhabits the spiny forests and savannah edges of dry and hot southwest Madagascar. Best time to find these animals is from the mid of February to the mid of March in the Didiereaceae forests nearby Toliara (Tuléar). The distribution area extends from Morombe to Antsokay south of Toliara, although we could always find most specimen about 15 to 50 kilometers north of Toliara.

Appearance and size:

Males reach a length of approximately 35 cm, females are much small with almost 20 cm. Both genders have a small, round nose appendage which is more distinct in males. Males have a dorsal crest made of large spines, in females this dorsal crest os only visible in the anterior part of the back. The casque is high, the body is bright green coloured with yellow accents, a white belly and a white lateral stripe that is interrupted several times. When stressed, this species show dark rings on both sides. Females have a colourful casque and violet cheeks with the violet colour continuing to the sides, some have a very strong violet pattern. Younger females often have only violet and blue dots on the cheeks.

Reproduction:

In the end of March until the beginning of April, females lay 10-15 eggs in dry and sandy ground. The eggs need approximately one year until young will hatch – they wait for the next rainy season.

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 Toliara (Tuléar) and surroundings is mainly one thing: Hot. In rainy season, daily temperatures rise easily to more than 30°C. In sunny places, it may even get 45°C. This is the location to look for every shady place you can get. And although it is called "rainy" season, precipitation in the south is lean. In good years, it is raining every couple of days from November to February. In worse years, it is raining even less.

During dry season, temperatures drop a little, but it remains very warm. In the night, temperatuers in July and August may drop even to 15°C, but days reach temperatures over 25°C without a problem. This large temperature drop is typical for the area. The dry season has only shot and very few rainfall.

Tageszeit = day time, Sonne = sun, Halbschatten = half shade, Schatten = shade

We have measured UVB data with a Solarmeter 6.5 in spring (end of March) 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 Toliara available yet.

Habitat:

The habitat of Furcifer antimena consists of spiny and dry forest which is only green during rainy season. In the dry season, the whole region is gray and withered. Where still is spiny forest, the ground is red sand and the forest is not really high, but the more so dense. Spiny plants, among them introduced opuntia, make the main part of the vegetation. Inbetween there may be Baobabs from time to time. But Furcifer antimena also inhabits secondary vegetation. It occurs in shrubs and bushes on sandy dunes and dried clay ground. During dry season, many specimen die because of the harsh environmental conditions.
