The Hawksbill turtle (Eretmochelys imbricata) is the second species that land on Pulau Selingan, though not as often as the Green Turtle.
The Hawksbill turtle or Penyu Karah is called after its hawk-shaped mouth. It is an endangered species because its shell is very popular for souvenir and jewelry trading. It is much smaller then the Green Turtle's one: 70 to 90 centimetres and it is famous because of its black and yellow colours. An adult Hawksbill Turtle can weigh up to 60 kilos.
The turtle species that appear most often on Pulau Selingan is the so called Green turtle (Chelonia mydas).
This Green turtle or Penyu agar gets its name because of its greenish body that feels soft. The Green turtle is also known as Soup Turtle, because it is often used in dishes that are very popular.
The Green turtle is born being a carnivour. It takes a few days before they turn into herbivours. After these days they stick with seaweeds and algaes for the rest of their long lifes. A Green turtle can make it to 100 years of age. An adult Green Turtle can reach a size of 1.10 metres and a weight of 150 kilos.
Like all turtles, the sex of the babies is determined by the temperature of the ground the eggs are laid in. If the ground is warm it will become mostly female, if it is cooler mostly males will be born. Every nesting a turtle can "produce" up to 140 eggs, and it takes 50 to 60 days until the baby turtles come out.
