Sea Turtles and their life span

Turtles appeared on earth more than 200 million years ago, the famous "living fossil." According to the records of the "Guinness Book of World Records, the longest lifespan of 152 years. It's worth the ancient god of longevity in animals. As sea turtles have the longest lifespan, so the coastal towns consider regard them as a long-lived mascot, such as human Songhe mainland as a symbol of long life, coastal sea turtle people also considered a symbol of sustainability. There are eight species of sea turtles, including four made in China, mainly in Shangdong, Fujian, Taiwan, Hainan, Zhejiang and Guangdong province in China. The largest number of green turtles turtles in China.

Sea turtles often have activities in the upper levels of their regular migration routes along the coastal waters. They mature at 20-30 years old. When the breeding season comes, they return to their "homeland". No matter how far it is, can save their place of birth, and there lay eggs. It is likely that they can not live as long as their breeding place of birth is broken.

The largest number of nests is 200 or so, the minimum is over 90. The number of eggs is more, but the incubation survival rate is very low. When the young turtles hatched, before they climbed out of the sand itself, and then hurried toward the ocean. It is full of danger, when the little turtles rise from the sand on the beach, a number of natural enemies to see the young life as a delicacy. To successfully reach the sea are only part of the young turtles, survivors growth and development in the sea, passing a new cycle of reproduction.

This is a very interesting question, "how the turtle to maintain gender balance." Sea turtles live mainly in the sea, not only will they breathe to the lungs, but can the full benefits of some of the special organs for obtaining oxygen directly from seawater. They are fully adapted to marine environment. Sea turtles are large and have large volume of business, their appetite is far greater than the turtle. They eat lots of fish, fish eggs, shrimp, crustaceans and molluscs and algae per day.

Their teeth are hard and durable, they can easily scale the little mollusk. The habits of the turtles, the secret of their longevity is nothing more than a big appetite, slow activity and a hard outer shell to protect.
Sea turtle is a treasure, delicious food and rich nutrients are not only our own sustainability, but also a highly nutritional supplement, people who eat them to live. As such, more and more people killed by eating.
