Masirah Island, the Sultanate’s southeastern largest island, is rich in ecological diversity.

There are two more types of turtles, the Olive Turtle that put its eggs on the shores of Masirah Island in numbers up to 150 turtles annually, and the Hawksbill Turtle, which nestles on Masirah Island and the Dimaniyat Islands.
