The Gila monster (Heloderma suspectum) is one of the most unusual lizards in North America. Like all reptiles, it is ectothermic (cold-blooded), depending on the environment to warm or cool its body. Its skin is covered in bead-like osteoderm scales that act like protective armour and give it a rough, bumpy appearance.
Gila monsters live in the deserts of the southwestern United States and northern Mexico. Because desert temperatures swing from extremely hot to cold, they spend most of their time in underground burrows, coming out mainly in the early morning or evening.
They are one of the world’s few venomous lizards. Instead of injecting venom like a snake, a Gila monster bites and chews so the venom flows into the wound through grooves in its teeth. The bite is very painful but rarely dangerous to humans.
Their diet includes eggs, young mammals, nestling birds, and carrion. With a slow metabolism, they can survive on only a few big meals each year and store extra energy as fat in their tails and bodies.
Although they look fierce, Gila monsters are slow-moving and shy, playing an important role in desert ecosystems as predators and scavengers.
