- [Narrator] With a lifespan able to reach as old as 69,
these iguanas can live as long as humans.
This is the Grand Cayman blue iguana.

Found only in Grand Cayman, the largest and western most
of the Cayman Islands, their blue skin becomes more
prominent when establishing territory
when other iguanas are nearby.
Males turn especially bright blue during breeding season,
but their blue skin isn't their only defining feature.
They have striking red eyes and excellent vision,
which enables them to notice shapes and movement
at long distances.
Listed as endangered due to human activity,
habitat loss, and being preyed upon by
free-roaming predators such as dogs,
cats, and rats, these beautiful blue lizards
face an uphill battle against extinction.
