Arboreal locomotion Arboreal locomotion Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. The earliest known tetrapod with specializations that adapted it for climbing trees was "Suminia",
Brilliant arboreal alligator lizard in protected areas such as Mario Dary Rivera Protected Biotope and Sierra de las Minas Biosphere Reserve. Brilliant arboreal alligator lizard The brilliant arboreal alligator lizard (Abronia gaiophantasma) is a species of lizard endemic to the mountains of east-central Guatemala, from the Sierra de las Minas east to the Chilascó region. It occurs at elevations of 1,600–2,650 m, and can be found in pine–oak and cloud forests of lower montane wet forests. Its extent of occurrence is estimated at only 750 km, and has been declared endangered. Threats to this species include habitat loss from agriculture, and the exportation of
