New Nocturnal Gecko Species Discovered in Madagascar

Nocturnal GeckoA new species of gecko has been found living among the crumbling remains of an old French fort in northern Madagascar. The gecko, nocturnal by nature, is a master of camouflage and seamlessly blends in with the surrounding rocks and fortress ruins, according to a new study.

Although researchers first found the new gecko species (Paroedura hordiesi) in 2004, when they spotted a male with a broken tail, a new genetic analysis and a close examination of its physical features now show that it is a distinct species.

After the scientists found more of the geckos around the French fort, they reported that the new species could measure up to 2.3 inches (5.8 centimeters) from their nose to the base of their tail. The creatures have long tails that can measure nearly the entire length of their bodies, up to 2.1 inches (5.3 cm)

The geckos also have square-shape adhesive pads on their toes, a feature that is unique to Paroedura geckos, and the related gecko genus, Ebenavia, the researchers said.

The newfound species has a relatively small habitat, spanning just 19 square miles (50 square kilometers). But the gecko is not alone in its territory — in the past few years, researchers have identified other new reptile species at the Montagne des Français Reserve in northern Madagascar, including new tree frogs, leaf chameleons, lizards and snakes.

It’s likely that other unknown reptile species live in this portion of the region’s limestone mountains, called a massif, the researches said. But many of the animals native to the area could be threatened by habitat destruction, they said.

In fact, the researchers asked that the new gecko species be classified as “Critically Endangered” on the Red List of Threatened Species, which is maintained by the International Union for Conservation of Nature, an international organization that tracks the status of animals, plants and fungi around the world.
