The Ultimate Guide: What Do Lizards Eat?

Have you ever paused to ask yourself, “What do lizards eat?” With over three thousand species across the globe, the answer can be as varied as the lizards themselves. Some prefer a carnivorous diet, munching on small mammals and insects, while others stick to a purely plant-based food source. Then there are the versatile omnivorous lizards who enjoy a mixed platter of both flora and fauna. Let’s delve into their fascinating dietary habits, whether you’re an aspiring pet owner or simply curious about these adaptable creatures.

Carnivorous lizards are strictly meat-lovers; insects and small mammals are their prime delicacies. If you’re considering having one as a pet, you need to be comfortable with providing live prey. Plenty of pet stores sell live crickets and worms, or for more convenience, you can get freeze-dried options available in bulk.

Among the carnivores, we have the geckos, tropical creatures that thrive in warm habitats augmented with heaters and light sources. While they might lack the cuteness of a puppy, they certainly carry their unique charm. Notably, there’s the leopard gecko, a great beginner-friendly option, typically munching on dusted crickets for the essential nutrients.

At the apex of the carnivorous lizards, we have the formidable Komodo Dragon. The sheer size of this creature allows it to feast on an expansive menu of mammals, from wild boar to the water buffalo. Consequently, with such a rich diet, the Komodo Dragon only needs around twelve large meals per year for a healthy lifestyle.

Switching gears, let’s talk about herbivorous lizards, such as the ever-popular iguanas. Their dietary preferences lean towards plants, favouring vegetables, fruits, and even flowers. However, some exceptions, like the spiny-tailed iguana, require a protein boost as babies. Mealworms, crickets, and even baby mice can provide this extra source of nutrients.
