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.
