The humble iguana may have have pulled off an epic migration millions of years ago, traveling from the coast of today’s Mexico to Fiji on rafts made of vegetation.

There are 45 different species of Iguanidae in the Caribbean and the tropical, subtropical and desert areas of North, Central, and South America, including the marine iguanas of the Galapágos and the chuckwallas in the American Southwest.

Iguanas may have pulled off a 5000 mile voyage on a raft of floating vegetation to get to Fiji. Researchers have long wondered how iguanas got to the collection of remote islands in the South Pacific.
