它们没有脑袋、腿、鳍和尾巴,但是它们并不是单单为了取悦人们的眼睛而生的,它们就是扇贝。那些散落在沙滩上的贝壳都曾经是一些动物的家,那些动物叫做海洋扇贝。每个贝壳都由一个底部和一个顶部组成,扇贝可以打开或是关上它们。那么海洋扇贝为什么要居住在贝壳里面呢?因为扇贝的躯体非常柔软湿润,如果没有一个坚固的贝壳来保护它,扇贝很容易被它的天敌吃掉。 They have no heads, legs, fins and tails, but they are not born solely to please the eyes of the people; they are scallops. The seashells scattered on the beach were once the homes of some animals called marine scallops. Each shell consists of a bottom and a top that the scallops can open or close. Why does the marine scallop live in the shell? Because the scallop’s body is very soft and moist, the scallop can easily be eaten by its natural enemies without a solid shell to protect it.
