6 Endangered Sea Turtles List Facts
Common species which can be seen in the sea all over the world. Some scientists say its old as dinosaurs, because their fossils were found since 145-208 million years ago. Their feet (also known as flippers) is part of them which make unique because they only have one pair and can be used for swimming across a sea or do immigration for thousand miles. Even it seems like old and slow one, don’t underestimate them! Sea turtles can swimming for 1,4-9,3 km/hours, and also can dive until 1200 feet!
Become great swimmer doesn’t make them prefer to live under water, instead they choose to live in shallow water or floating between sea weeds bed. Classified into vertebrata make sea turtles need to go to surface sometime to take a breath after dive for some minutes and furthermore, they will come to any coasts for breeding seasons.
To found a perfect coasts for laying their eggs, female sea turtles always has some categories and can swimming across sea for thousand miles to found the best one.
Silence and sandy coasts is perfect coasts to them because it will protect them for any predators who’s ready steal their eggs. Sunshine and some noises are enemy for them too because it will make predators found their baby easily and the baby will confused how to walk back to the sea.
After female sea turtles reach the perfect coasts, they will digging sands for about 20-40 cm to place their eggs there (so predators cant found it) and will leave their nest after 40-60 days. Predators who’s like to hunt sea turtles are crabs, birds, rats, another big fishes, and human.
Sea turtles are often over exploitation by human because they have so much advantages for humans and this make sea turtles as endangered one. Like another sea species, sea turtles has some types and almost their type classified as endangered. Here you go, some types of Endangered Sea Turtles List and their unique behavior:
1. Green Sea Turtles (Chelonia Mydas)
Large one, live in tropical and subtropical coasts and will getting into surface for sun bathe. One type which only classified into vegetarian, with algae and sea grass are their favorite food, and they will also eat soe crabs, jelly fish, or sponges.

Breeding season of green sea turtles usually occurs in late spring until early summer and will occurs every two years after female reach their sex maturity. Their nests usually near sea so after baby sea turtles hatched, it can run easier and faster to the sea and survived for become prey from any predator in the coast.
Like another type, green sea turtles need to going to surface for breathe after dive for 3-5 minutes. When they already mature, its easy to know between males and females green sea turtles because males green sea turtles has longer claws on the front flippers and larger tails.
Some countries are trying to protect this type from over exploitation with make some conservation in: Bali (Indonesia), Sabah (Malaysia), United Kingdom, and Tortuguero National Park.
2. Leatherback Sea Turtles (Dermochelys Coriacea)
The biggest and longest sea turtles, which their average weights are 300-500 kg and their length are around 130-183 cm. The largest and heaviest was recorded almost 916 kg and 305 cm. Leathery, black and spotted with white or yellow color which make this type different from the others.
Another uniqueness is they can stay for 35 minutes under water and only need once time to go to surface for take breath. Their speed to swim is about 1,-10,08 km/hour and they belong to fast swimmer and can across a sea for about 6,000 miles to found best coast for breeding seasons.
Breeding seasons usually occurs at tropical areas. Females leatherback sea turtles usually go to North Alaksa and South Africa to lay their eggs and it can be reach 100 eggs each holes. Once baby sea turtles is hatched, their length only about 5-8 cm and it needs around 2 months for incubation. Unlike another type, they might be not come back to coasts where they were hatched because they prefer coasts with soft sand and some dark forested area.

Jelly fish, conchs, crabs, fishes are their mainly foods and that’s why they classified into carnivore even they also eat sea weed and sargassum too. Their powerful jaws make them able to eats some hard-shelled prey.
Such as whelks, och, clam, and sea urchins. Atlantic, Pacific, and Indian Oceans area their habitat because they live in tropical regions.
Their life span are around 47-67 years old and females will reach their sex maturity when they already 35 years old. After mature, they will have their mating season every 2-3 years and will back to the coast where they were hatched.
When mating season already started, they usually moved into sub-tropical areas, like from Greece or Turkey to Israel and Libya. In the southern US, mating seasons usually occurs in late May to early Junes and females will lay their eggs between late April and early September.

This type need 20 years to reach their sex maturity and mating seasons usually occurs every three years. Mexico, Seycheilles, Indonesia, and Australia are places which usually become their nesting seasons and will start around April until November. Usually each net contain 100-140 eggs and needs two months until they’re hatched.
Beside their hard shells make them has less predators, this population already decreased about 80% over last century because over exploitation and so much illegal trade in some countries. Human not only hunt for their meat, but also their eggs because it can be used as souvenirs, jewelry, ornaments, or traditional medicine.
To protect themselves from any predators, young hawks-bill usually floating among sea plants near coasts because they cant dive yet.

Baby Kimp’s Ridley only 3,8 cm and 14 gram and they will floating between sargassum seaweeds beds for first year. Male and females of this type can be known since they’re hatched; because when the eggs are hatched below 29,5 celcius usually they will become male sea turtles. Colors of this type will also change when they’re mature, like from dark-gray color when they’re young and will become olive green and yellow when they’re adults.
