Garden lizards in the wild typically eat snails, insects and caterpillars. In captivity, garden lizards have a diet that mainly consists of crickets and other small bugs .
California lizards eat mostly ants, grasshoppers, spiders and beetles. They have a small row of teeth on each jaw and teeth on the roof of their mouths. Lizards snatch their food with long, sticky tongues, crush it in their jaws and swallow it with very little chewing.
The various different types of lizards include anoles, chameleons, geckos, American legless lizards, monitor lizards, agamids, iguanas and earless lizards. Lizards belong to the class Reptilia and order Squamata. There are approximately 5,000 lizard species found in the order Squamata.
Lizards are distributed throughout the world, and as the San Diego Zoo notes, most of them live on the ground. Other common lizard dwelling places are underground burrows (especially in deserts), under rocks, marshy bogs and in trees.
The average lifespan of a lizard usually runs between one and 30 years, with a median of 10 years. Because there are over 5,000 different species of lizards, the lifespan varies from species to species.
The most effective method of keeping lizards away is to make the area less hospitable. Commercially available chemical and electric repellents sometimes work, but these are potentially harmful to children and pets.
Most lizards are omnivores, however, what a lizard eats is largely influenced by its size. With over 3,800 different species of lizard, there is no set diet between them.
Common lizards feed on insects, such as flies, grasshoppers and spiders, according to the Surrey Amphibian and Reptile Group. They also eat invertebrates, including earthworms, small snails and centipedes.
Small lizards can be carnivorous, herbivorous or omnivorous. Small lizards may eat a variety of insects, plants or a mixture of the two. Most lizards have a high metabolic rate and need to eat several times a week.
Types of pet lizards include the leopard gecko, the crested gecko, the bearded dragon, the green iguana and the Chinese water dragon. The pet lizards' sizes, how easy they are to care for and the costs of maintaining them determine their suitability for either the beginner or the expert keepers.
