Nile Monitors are large, semi-aquatic lizards native to Africa, known as Africa's largest lizard, growing up to 8 feet long with powerful tails for swimming and sharp claws for climbing. They are opportunistic carnivores eating eggs, fish, small mammals, and more, basking by day and hiding at night, often near water. These intelligent reptiles use forked tongues for scenting, lay eggs in termite mounds, and can hold their breath underwater for up to 15 minutes, impacting ecosystems in Florida where they are invasive.
