The Kiribati islands are located in the central Pacific Ocean making it jam-packed with rare animal species native to these islands. The islands host triggerfish (Xanthichthys greenei) that reside in greater depths of the ocean. Candy scale picnic gobies (Trimma squamicana) are more rare in other parts of the world, but are fairly common on the islands. They are light in color and are found at depths of 30 to 150 feet. The y-barred sandperch (Parapercis lata), is a shallow-dwelling fish with a white body and patches of red.^[4]
