Lizards are novel pets, but equipping oneself with information before purchasing is prudent. Their price is not great, but acquiring the more costly and proper diet, light, environment is vital in averting often, preventable health problems such as metabolic bone disease. Preventing potential for salmonella transmission from reptiles and amphibians is also essential. Some good lizards for beginners are green anoles, bearded dragons, blue-tongued skinks, and leopard geckos. Chameleons, other geckos, iguanas, and savannah monitors add challenge for non-beginners.
Lizards are reptiles of the order Squamata, normally possessing four legs and external ear opening. The adult length of species within this order range from a few centimeters (some Caribbean geckos) to nearly three meters (Komodo Dragons).
