What lizards are
Lizards are a broad and diverse group of squamate reptiles. They include thousands of species with different body forms, habitats, and life histories. Most have four limbs, movable eyelids, and external ear openings, distinguishing them from snakes.
What they eat
Lizard diets depend on the species and environment. Many eat insects and other invertebrates, while others are omnivores or herbivores, consuming fruit, leaves, eggs, or small vertebrates.
How they reproduce
Most lizards reproduce through internal fertilization. Many species lay eggs, but some retain the eggs inside the body and give birth to live young. Lifespan varies from a few years to decades.
In short
- Lizards are reptiles in the order Squamata.
- Their diets vary widely by species.
- Most lay eggs; some give live birth.
