Tracheloptychus petersi is a small lizard from the family of girdled lizards. It lives only in Madagascar and has hard keeled scales on its back and sides.
This species is distinguished by keeled scales on the body that protect from enemies and help crawl on rocks. It is important for Madagascar's nature because it eats insects and serves as food for snakes and birds.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
