After half an hour of seeking out crabs unsuccessfully, we had to give up and lie on the hammocks, waiting till midnight when the sea turtles started to lay eggs. Fifteen minutes later, a forest warden shouted in excitement, "I have found blue land crabs! Let's go and see!" Holding a 1kg crab which kept wriggling in his hands, he said, "Blue land crabs crawl fast and hide very carefully. So it is very difficult to find them. The number of these kinds of crabs is very small, therefore we are building a plan to preserve them in the future." After seeing the rare crabs, everybody moved to the beach to wait for the turtles. It was nearly 11pm but there seemed no trace of any commotion that crabs create. The sea at night was so silent, except for the sounds of the waves that sometimes struck ashore. Con Dao Island At about 12pm, by following the big footprints in the sand, we approached the position where a turtle was digging a hole to prepare to lay eggs. "She is making a very deep hole to protect her eggs," explained the forest warden while shining his electric torch at the back of the turtle. Shortly afterwards, each tiny egg, as small as a ping-pong ball, started to fall into the hole. Everyone was very excited and curious to see such a rare and interesting scene. The result of that night was 87 eggs laid by the 200kg sea turtle. After giving birth successfully, the mother turtle quickly used her two rear legs to cover the hole with sand and moved to the sea. Noting down the details about the size the mother turtle's shell, the forest warden started to dig the hole in which the turtle had just given birth to check the quality of the eggs. "This mother turtle laid fewer eggs than usual, because each turtle is expected to have more than 100 eggs, 80 or 85% of which will be hatchable," he said, while quickly moving the eggs into a net. The eggs looked so cute that we could not resist asking for the forest warden's permission to hold and gaze at them in our hands. He also enthusiastically showed us how to examine the eggs properly and provided us with important information about two popular kinds of sea turtles in the area. According to the board of management of Con Dao National Park, the eggs are moved to a higher position in order to prevent sea water from spoiling them. Additionally, the direct interference of the hatching temperature will decide the sex of the baby turtles, which helps in balancing the male to female ratio. The movement also plays a very important role in preserving such precious sea animals, whose babies only have 1/1,000 or even 1/10,000 chance of survival. Not only learning about the process of giving birth and development of sea turtles, we also had a chance to release the baby turtles into the sea ourselves. Three of us held a basket which contained hundreds of baby turtles and moved towards the sea. As soon as they landed on the sand, the turtles immediately swam away in the silent night, riding along the white frothy sea waves. What an interesting lesson we had learnt about nature, precious sea animals' preservation and environment protection.  vietnam travel
