Brygoo, Blanc & Domergue, 1974
Origin of the species name:
Édouard-Raoul Brygoo (later working at the Natural History Museum in Paris, France), Charles Pierre Blanc and Charles Antoine Domergue from the then Institut Pasteur in Antananarivo, Madagascar dedicated the species to their colleague Paul Griveaud. Griveaud was an entomologist and described numerous insect species of Madagascar.
Brookesia griveaudi lives in foliage, shrubs and low branching in Northeast Madagascar. Its distribution area builds a long triangle between Antalaha, Sambava, and Maroantsetra and includes the national parks of Marojejy, Anjanaharibe-Sud, and Masoala. During the daytime, you can find it directly in the foliage or short above.
Appearance & size:
With a maximum total length of 11 cm, this species belongs to the larger leaf chameleons. Laterally along the back, it has 9 to 10 tubercles on each side that are continued on the tail. Brookesia griveaudi has a well developed pelvic shield, that the otherwise quite similar species Brookesia superciliaris does not have. Like the latter, individuals of Brookesia griveaudi have big, pointed bony extensions above the eyes. Brookesia stumpffi, that has a similar well developed pelvic shield, has in contrast to Brookesia griveaudi rounded bony extensions above the eyes. The specimens we found all had brown coloration with a dark stripe along the back, right between the tubercles. But according to literature, this stripe is not always visible in this species.
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 pictures show the habitat of Brookesia griveaudi between Camp Mantella and Marojejya in Marojejy. In the upper part between both camps and around Camp Marojejya we have found these animals mostly. The rainforest here consists of huge tree giants and slippery, mossy, round stones in very lush undergrowth. Ferns, lianas, and moss dominate the scene. You can find these chameleons walking on dead wood or climbing on low twigs.
