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]
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.
The green iguana (Iguana iguana), also known as the American iguana or the common green iguana, is a large, arboreal, mostly herbivorous species of lizard of the genus Iguana. Usually, this animal is simply called the iguana. The green iguana ranges over a large geographic area; it is native from southern Brazil and Paraguay as far north as Mexico.
The forest monitor lizard can grow to more than 2 m (6 ft 7 in) in length, and weigh up to 15 kg (33 lb), or possibly more. [4] Its scaly body and legs are a blue-black mottled with pale yellow-green dots, while its tail is marked in alternating segments of black and green. [ 5 ]
The herbivores consist of iguanines, some agamids, and some skinks. [33] Most lizard species and some snake species are insectivores. The remaining snake species, tuataras, and amphisbaenians, are carnivores. While some snake species are generalist, others eat a narrow range of prey - for example, Salvadora only eat lizards. [33]
There are few lizards less suited to life in captivity than the Nile monitor. Buffrenil (1992) considered that, when fighting for its life, a Nile monitor was a more dangerous adversary than a crocodile of a similar size. Their care presents particular problems on account of the lizards' enormous size and lively dispositions.
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 ]
Lystrosaurus (/ ˌ l ɪ s t r oʊ ˈ s ɔːr ə s /; 'shovel lizard'; proper Ancient Greek is λίστρον lístron ‘tool for leveling or smoothing, shovel, spade, hoe’) is an extinct genus of herbivorous dicynodont therapsids from the late Permian and Early Triassic epochs (around 248 million years ago).
