4. Reticulate Gila Monster
The reticulate gila monster is found mainly in Mexico and the USA, in deserts and rocky areas. They have flattened, triangular shaped heads, with the males having bigger heads than the females. They have long, fat and cylindrical torso, with females having a broader torso. Their diet consists of reptile eggs, birds and rodents. Their hunting skill is empowered by their strong sense of smell and hearing. They can hear vibrations of their prey from far away and smell buried eggs. The large torso and tail are used to store fats and water, enabling them to survive in deserts. The dry and flaky scales prevent excessive loss of water from their bodies.
