Nearly Extinct Marine Reptile Facts – Turtles are currently one of the types of reptile animals that can be found in the world, but this reptile animal is one of the most extinct animals.
Turtles are a group of reptiles that can be found in all oceans in the world, except in the polar regions. It is known that there are 7 species of turtles, 6 of which are in a vulnerable condition. The main factors that cause a reduction in turtle populations are hunting, habitat loss, entanglement in fishing nets, marine pollution, and climate change.
1. Turtles have lived on earth for millions of years
Turtles are very old organisms, they have lived on earth for more than 110 million years. The turtles persisted against climate change that had killed the dinosaurs.
The turtle’s upper body is protected by a shell called a carapace. Unlike tortoises on land, turtles cannot hide their heads and feet in their shells. That reason also makes them more vulnerable when dealing with predators.
2. Female turtles return to the same beach to lay eggs
Sea turtles spend most of their life in the ocean. Females can be seen on the beach only during the spawning season. During the spawning season, the female turtle will return to the same beach where she hatched. He will find the right beach even after 30 years of being gone.
Turtles lay their eggs in sand holes. The nests are not easy to spot because the turtles cover them with an additional layer of sand. Depending on the species, each turtle nest is usually found 60-200 eggs.
3. The sex of the turtle is determined by the temperature of the eggs
Temperature really determines the sex of the baby turtles. Females will be born if the egg temperature is high and males if the egg temperature is low.
The young turtles hatch at night and they take advantage of the moonlight to find their way to the sea. Too much light on the beach can disturb and confuse young turtles.

4. Turtles are good swimmers and can cover long distances
Turtles walk slowly on sand because their fins are adapted for swimming, not walking. They are good swimmers who can travel great distances. Leatherback turtles can swim up to 19 thousand km, which is the same distance between Indonesia and Oregon, United States.
Turtles do not have teeth, but their mouths adapt to each type of food they are used to eating. Green turtles are vegetarian animals that eat seaweed, while other turtles eat crabs, clams, jellyfish and sea cucumbers.
The turtle will grab hold and eat the plastic floating in the water because it looks like a jellyfish, and that can kill the turtle.
5. The size of the turtle depends on the species and its lifespan is quite long
Turtles have lungs and breathe oxygen. They spend most of their time underwater, but they need to come to the surface to breathe in oxygen.
The size of the turtle is different for each species. Kemp’s Ridley turtles weigh up to 35-45 kg, while leatherback turtles can weigh more than 100 kg. A turtle can live between 70-80 years.
