A group of German and American scientists have discovered what they believe is the smallest chameleon in the world on the island nation of Madagascar.

Researchers from Munich, Darmstadt and Braunschweig, as well as California, have named the 16 millimetre-long beast Brookesia micra – Brookesia is the name of the genus the chameleon belongs to and micra represents the animal’s small size.

The chameleon lives in forests and eats insects and tiny mites, the scientists discovered. It is brown in order to blend in with the trees and doesn’t change colours like its better-known chameleon cousins.

Other vertebrates – such as some fish and frogs – are even smaller than Brookesia micra. But the endangered chameleon is thought to be the smallest of its kind.

“These tiny reptiles are threatened with extinction,” said Miguel Vences from Braunschweig’s technical university.

Overall, the scientists discovered four new species of extremely small chameleons during their expedition to one of the most biologically diverse countries on the Earth. Nearly half of the world’s 193 known species of chameleon are thought to live only in Madagascar, which is off the south-western coast of Africa. That includes the world’s largest at 70 centimetres and now the world’s smallest.

Vences and his colleague, Frank Glaw of the Bavarian State Collection of Zoology, have alone discovered 140 new animal species in Madagascar and named them scientifically.

Their research is being published in the scientific journal PLoS ONE.

A Malagasy-German research team has discovered a new primate species in the Sahafina Forest in eastern Madagascar, a forest that has not been studied before. The name of the new species is Gerp's mouse lemur (Microcebus gerpi), chosen to honour the Malagasy research group GERP (Groupe d'Étude et de Recherche sur les Primates de Madagascar).

They captured several mouse lemurs, measured them, took photos and small biopsies for genetic studies, and released them again. Prof. Ute Radespiel, Institute of Zoology of the University of Veterinary Medicine Hannover, analysed the samples and the morphological dataset, and confirmed that the animals from the Sahafina Forest belong to an undescribed species of the small nocturnal mouse lemurs.

"We were quite surprised by these findings. The Sahafina Forest is only 50km away from the Mantadia National Park in eastern Madagascar, which contains a different and much smaller species, the Goodman's mouse lemur," commented Prof. Radespiel. In contrast, the Gerp's mouse lemur belongs to the group of larger mouse lemurs, i.e. has a body mass of about 68g, and is therefore almost "a giant" compared to the Goodman's mouse lemur (ca. 44g body mass).

The distribution of the Gerp's mouse lemur is probably restricted to the remaining fragments of lowland evergreen rain forest of this region in eastern Madagascar. Continuing deforestation poses a serious threat for these animals. The researchers from Hanover/Germany, and Madagascar published their discovery together in the journal Primates.
