What does an iguana eat?

Iguana's are Herbivores. They eat dark, leafy green vegetables, such as, collard greens, mustard greens, parsley, dandelion greens, escarole, spinach, and kale. Iceberg lettuce should be avoided as it offers no nutritional value and iguanas can become hooked on it, refusing to eat other foods. Other vegetables that are good to offer include green beans, green peppers, frozen mixed vegetables, squash, and fruits, such as, bananas, Apples, mangos, papaya. Iguana's eat flowers....pretty much all squash....dark greens.....wide variety of fruit.
Mostly algae.
