龟族种类很多,不论在海洋中或是陆地上,都有龟类活动的场所。生活在海洋中的最大的龟是棱(leng)皮龟,它体重有500公斤,龟壳长2米,生活在印度洋和太平洋热带地区的海水中。只有快到产卵(luan)的时候,才爬到偏僻(pian pi)的岛屿上。每只雌(ci)海龟一生可产500一1000个蛋,但卵的孵化率(lu)较低。海龟从不会忘记它诞(dan)生的故乡,每年都会成群结队地返回故地筑巢(cha0)繁殖(fan zhi)。 Many species of turtles, both in the ocean or on land, there are turtle activities. The largest turtle living in the ocean is the leng turtle, weighing 500 kilos and 2 meters long and shell-turtle shell, which lives in seawater in the Indian and Pacific tropics. Only reached the luan when it climbed the pian pi island. Each female (ci) turtle can produce 500 to 1000 eggs for a lifetime, but the egg’s hatching rate (lu) is low. Turtles never forget the birthplace of their birth, and return to their hometown for fan zhi in droves every year.
