40 percent of Madagascar’s terrestrial reptiles are threatened with extinction due to habitat loss and over-collection for the pet trade, reports the International Union for Conservation of Nature (IUCN) in its latest update of the Red List of Threatened Species. Experts from around the world conducted the assessment of 370 native terrestrial reptile species found in Madagascar, including snakes, lizards, crocodiles, turtles, and tortoises. Overall 22 were found to be critically endangered, or at immediate risk of going extinct.
