Peters's Keeled Cordylid (Tracheloptychus petersi), ready to run

Along with its sibling species Tracheloptychus madagascariensis, this is one of the two small Madagascar lizards in the family Gerrhosauridae with keeled scales (the Zonosaurus species all have smooth scales). The "Cordylid" part of the common name is a leftover from when all these lizards were considered part of the family Cordylidae.
