1) "All lizards eat flies and other insects. Many species of lizards are vegetarians, consuming only leaves, flowers and fruits. Some species of lizards eat primarily plant matter with a few insects, other invertebrates, or small animals now and then. Others eat primarily invertebrates or only animals, including other lizards, snakes, amphibians, fish, birds and mammals. You cannot make a carnivorous reptile into a vegetarian and you should not feed animals to vegetarian lizards. Doing either will result in serious health problems and an early death."

A bearded dragon eats crickets, grasshoppers, mealworms and earthworms. They also eat green leafy vegetables but no iceberg lettuce. Small pieces tomatoes, apples, pears, grapes, oranges, cooked potatoes, melon, peas, and strawberries can be added to their diet. Carrots should be grated. You also can add powdered vitamins and minerals to their food. This should only be once or twice a week."

"Only the very largest lizard species pose threat of death; the Komodo dragon, for example, has been known to attack and kill humans and their livestock."
