Brookesia tedi occurs sympatrically with Brookesia karchei in Marojejy national park in the northeast of Madagascar. It lives similar to its larger relative at tree roots, in foliage and near mossy stones on the ground. We were able to find Brookesia tedi between Camp Marojejya and Camp Simpona before its actual description. The animals don’t occur lower than 1200 m.
Appearance & size:
This species remains very small with a total length of just 30 mm. Along the back, the animals carry a row of eight to ten laterovertebral spines, which do not continue on the tail. They have a characteristic pelvic spine on both sides of the hip. Brookesia tedi is very inconspicuous in colour. The body can show different shades of brown and black spots on the body as well as lines behind the eye. Brookesia minima can be distinguished quite well from Brookesia karchei, which occurs in the same habitat and is only slightly larger: Brookesia karchei has clearer supraocular cones, in Brookesia tedi the head shape is rather round, similar to that of Brookesia peryrierasi. Furthermore, B. karchei has spines on the tail, B. tedi does not have these.
Good to know:
This species is part of the minima group, which includes the smallest chameleons of the world.
Data will come soon.
Marojejy mainly consists of rainforest that extends over the eponymic sacred mountain at elevations of 800 to maximally 2100 m above sea level. In the highest areas, climate is cool and vegetation sparse, but most chameleons live in the warmer dense rainforest below.
In Marojejy, there is few difference between rainy and dry season. Humidity is always very, very high. In rainy season, precipitation is more intense with rainfalls that may last for days and sometimes are accompagnied by heavy storms. In dry season, temperatures are a little lower, but it never becomes really cold. And it stills rains almost daily. It really cannot become dry in Marojejy during "dry" season. Humidity is the main key factor of this rainforest.
We have measured UVB data with a Solarmeter 6.5 in spring (end of March until 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.
The following photos show extracts from the habitat of Brookesia tedi between Camp Marojejya and Simpona in Marojejy. The rainforest consists of giant jungle giants, slippery, mossy, round stones and very lush undergrowth. Ferns, lianas and moss determine the picture. The chameleons can only be found with a very good search near tree roots and in dense foliage.
