What is the length or height of a marine iguana?

Marine iguanas typically range in length from about 3 to 5 feet (0.9 to 1.5 meters), depending on the species and individual. They can weigh between 10 to 20 pounds (4.5 to 9 kg). The males are generally larger than the females, especially during the breeding season. Their unique adaptations allow them to thrive in the marine environment of the Galápagos Islands.
