[2] It consists of 3 islands - Selingaan, Little Bakkungan and Gulisaan (often spelt with -an instead of the traditional -aan), including the surrounding coral reefs and ocean.On 1 August 1966, the first turtle hatchery in Malaysia was established on Selingan, funded entirely by the Sabah state government.However, park rules and regulations are strictly enforced and visitors are not allowed on the beach from sunset to sunrise so as not to disturb the turtles.The chamber is no different from that of the turtle: between 60–75 cm deep, in the sand, but within a protected hatchery to make it impossible for natural predators to dig the nests open.Since temperature determines the sex of the turtles part of the hatchery is shaded, while the rest remains under the open sun.
