A tree frog is any frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several unrelated lineages of frogs among the Neobatrachia have given rise to tree frogs, even though they are not closely related to each other. Many millions of years of convergent evolution have resulted in almost identical morphology and ecologies. In fact, they are so similar as regards their ecological niche that where one group of tree frogs occurs, the other is almost always absent. The last common ancestor of the tree frog groups lived long before the extinction of the dinosaurs.

Lizards are a widespread group of squamate reptiles, with more than 5600 species, ranging across all continents except Antarctica as well as most oceanic island chains. The group, traditionally recognized as the suborder Lacertilia, is defined as all extant members of the Lepidosauria, which are neither sphenodonts nor snakes - they form an evolutionary grade. While the snakes are recognized as falling phylogenetically within the Toxicofera clade from which they evolved, the Sphenodonts are the sister group to the Squamates, the larger monophyletic group, which includes both the lizards and the snakes.

Lizards typically have feet and external ears, while snakes lack both of these characteristics. However, because they are defined negatively as excluding snakes, lizards have no unique distinguishing characteristic as a group. Lizards and snakes share a movable quadrate bone, distinguishing them from the sphenodonts, which have a more primitive and solid diapsid skull. Many lizards can detach their tails to escape from predators, an act called autotomy, but this ability is not shared by all lizards. Vision, including color vision, is particularly well developed in most lizards, and most communicate with body language or bright colors on their bodies as well as with pheromones.

The adult length of species within the suborder ranges from a few cm for chameleons like Brookesia micra and geckos like Sphaerodactylus ariasae to nearly 3 m (9.8 ft) in the case of the largest living varanid lizard, the Komodo Dragon. Some extinct varanids reached great size. The extinct aquatic mosasaurs reached 17 m (56 ft), and the giant monitor Megalania prisca is estimated to have reached perhaps 7 m (23 ft).
