A real-life blue dragon that can live as long as humans

H. Michael Miley

These large lizards’ average body length and weight are 1.5 meters (5 feet) and 14 kg, respectively (30 pounds). These lizards, predominantly herbivorous, prefer to eat leaves and stems in addition to fruits and flowers. They have occasionally been seen eating earth, insects, feces, and fungi.

Blue iguanas live in arid environments like xerophytic shrublands. They love to spend their day in the sunlight. With a population estimate of about 450 individuals, the Grand Cayman blue iguanas are classified as an Endangered species on the IUCN Red List.
