Green Iguana

Green Iguanas vary in color from green to brown. They usually weigh about 10-15 pounds (4.5-6.8 kg) but can weigh up to 40 pounds (18 kg). They can grow to be up to 6 or 7 feet (1.8 to 2.1 m) long. Green Iguanas have a serrated crest along their back and a large dewlap hanging from their chin. Males have large scales under the ear. They use their powerful legs to swim and climb trees.
