The recent discovery of a large number of small-bodied herbivorous lizards (>100g; liolaemids) living in South America has forced scientists to rethink the physiological constraints faced by herbivorous lizards. Many of these lizards live at higher latitudes or elevations, and therefore, in much cooler climates than those seen in the tropics. [5]
The dentitions of lizards reflect their wide range of diets, including carnivorous, insectivorous, omnivorous, herbivorous, nectivorous, and molluscivorous. Species typically have uniform teeth suited to their diet, but several species have variable teeth, such as cutting teeth in the front of the jaws and crushing teeth in the rear.
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Reptiles, from Nouveau Larousse Illustré, 1897–1904, notice the inclusion of amphibians (below the crocodiles). In the 13th century, the category of reptile was recognized in Europe as consisting of a miscellany of egg-laying creatures, including "snakes, various fantastic monsters, lizards, assorted amphibians, and worms", as recorded by Beauvais in his Mirror of Nature.

This is a checklist of American reptiles found in Northern America, based primarily on publications by the Society for the Study of Amphibians and Reptiles (SSAR). [1] [2] [3] It includes all species of Bermuda, Canada, Greenland, Saint Pierre and Miquelon, and the United States including recently introduced species such as chameleons, the Nile monitor, and the Burmese python.
Uromastyx is a genus of lizards in the family Agamidae. The genus is native to Africa and the Middle East (West Asia). Member species are commonly called spiny-tailed lizards, uromastyces, mastigures, or dabb lizards. Lizards in the genus Uromastyx are primarily herbivorous, but occasionally eat insects and other small animals, especially young ...
Iguana (/ ɪ ˈ ɡ w ɑː n ə /, [4] [5] Spanish:) is a genus of herbivorous lizards that are native to tropical areas of Mexico, Central America, South America, and the Caribbean. The genus was first described by Austrian naturalist J.N. Laurenti in 1768. [6]
The lizards may be found at elevations up to 4,500 ft (1,370 m). [5] Primarily herbivorous, chuckwallas feed on leaves, fruit, and flowers of annuals and perennial plants; insects represent a supplementary prey. [5] The lizards are said to prefer yellow flowers, such as those of the brittlebush (Encelia farinosa). [5]
