Did you know that iguanas undertook one of the longest known overwater migrations from America to Fiji?
Researchers have proposed that Fiji's native iguanas reached the islands by travelling nearly 8,000 kilometers on mats of floating vegetation. Genetic studies indicate they share a common ancestor with desert iguanas from the American Southwest, suggesting overwater rafting was a plausible arrival route.
