Cope's arboreal alligator lizard Cope's arboreal alligator lizard Cope's arboreal alligator lizard ("Abronia aurita") is a species of lizard found in two isolated locations in Guatemala, one in the Alta Verapaz Department and one in the Jalapa Department. These lizard are found only in high altitudes of 2,000 to 2,600 feet above sea level, on the west and south sides of the mountain ranges. This lizard is one of 28 species of alligator lizards, most being arboreal, meaning they live in trees. These omnivores are considered endangered because of their small population size and they face extinction due to habitat degradation and from pressures
Arboreal locomotion gravity. Many arboreal species lower their center of mass to reduce pitching and toppling movement when climbing. This may be accomplished by postural changes, altered body proportions, or smaller size. Small size provides many advantages to arboreal species: such as increasing the relative size of branches to the animal, lower center of mass, increased stability, lower mass (allowing movement on smaller branches), and the ability to move through more cluttered habitat. Size relating to weight affects gliding animals such as the reduced weight per snout-vent length for 'flying' frogs. Some species of primate, bat, and all species of sloth achieve
