Lizards are eaten by birds, mammals, snakes and other lizards. Baby lizards are especially vulnerable to predators of all kinds because they receive no maternal protection. Lizard eggs are eaten by skunks, badgers and snakes.
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.
A lizard can live without food varies from species to species. Adult bearded dragons can survive for up to three weeks without eating, while adult leopard geckos can live for over a month without eating. It also depends on whether the lizard is an adult or a baby.
The lizard has a wide variety of predators, including birds, snakes and even other lizards. When being chased or attacked by predators, lizards may swell up, hiss, break off their tails to escape or even change colors to blend in with their surroundings.
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.
Most species of lizard are quadrupedal and crawl using their four limbs and tail. Certain species are legless and slither like snakes. Some lizards, such as geckos, can adhere to vertical or inverted surfaces and move freely on them.
Lizards communicate through body language, sound and visual displays, such as posturing and gestures, in addition to bright colors and even barking or hissing. These communications are used to ward off rivals or potential predators and to attract mates.
