A small body size would allow these lizards to take advantage of the brief warm periods experienced at high latitudes or elevations, which a larger lizard would otherwise not be able to exploit. [5] These animals illustrate the breadth of information that remains unknown with regard to herbivorous lepidosaurs.
An adult salamander generally resembles a small lizard, having a basal tetrapod body form with a cylindrical trunk, four limbs, and a long tail. Except in the family Salamandridae, the head, body, and tail have a number of vertical depressions in the surface which run from the mid-dorsal region to the ventral area and are known as costal ...
This contrast with the pleurodont condition found in the vast majority of lizards, where the teeth are attached to the inward-facing surface of the jaw. The teeth of the tuatara are extensively fused to the jawbone, making the boundary between the tooth and jaw difficult to discern, and the teeth lack roots and are not replaced during the ...
Lizard is the common name used for all squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, [1] ranging across all continents except Antarctica, as well as most oceanic island chains.
Iguanas have varying types of scales covering different areas of their body; for example, some large, round tuberculate scales are scattered around the lateral region of the neck among smaller, overlapping scales. [12] The scales on the dorsal trunk of their bodies are also thicker and more tightly packed than those on the ventral sides. [12]
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] The remaining lizards are omnivores and can consume plants or insects. The broad ...
Like many other lizards, including the frilled lizard and basilisk, the collared lizard can run on its hind legs, and is a relatively fast sprinter. Record speeds have been around 16 miles per hour (26 km/h), much slower than the world record for lizards (21.5 mph or 34.6 km/h) attained by the larger-bodied Costa Rican spiny-tailed iguana ...
