How Iguanas Crossed the Pacific to Fiji: A Tale of Survival and Evolution

April Joy Jovita

The presence of iguanas in Fiji has puzzled scientists for years. Unlike other Pacific islands, Fiji is home to two unique species of iguanas—the Fiji-banded iguana (Brachylophus fasciatus) and the Fiji-crested iguana (Brachylophus vitiensis).
