问号粉碎机:秋天来了,又到了吃海鲜的好时候了。在超市、海鲜饭店里我们会看到各种鲜活的海产品,可是也有一些从来就是以冷冰冰的方式面对我们的,比如带鱼。我们在陆地上从来没有看到鲜活的带鱼,这是为什么呢?要想解答这个问题,我们先来看看带鱼的生活习性和生活环境。带鱼又叫刀鱼、牙带鱼,是鱼纲鲈形目带鱼科动物。带鱼分布比较广,以西太平洋和印度洋最多,我国沿海各省均可见到,其中以东海产量最高。带鱼是生活在深海里的深水鱼,一般生活在水面下40米~50米深处。通过学习液体压强知识,我们知道,在海洋中,越往海洋底部走,海水所产生的压强就越大。所以,生活在深海之中的带鱼要想生存,它体内的压强就必须和深海中的压强保持一致。也就是说,带鱼体内的压强也很大。当带鱼被我们捕捞上来离开水面时,由于外界
Question mark grinder: autumn is coming, it is time to eat seafood. In the supermarkets, seafood restaurants we will see a variety of fresh seafood, but there are also some have been facing us in an icy way, such as octopus. We have never seen fresh octopus on land, which is why? To answer this question, let’s take a look at the living habits of octopus and living environment. Fish and fish, also known as sabers, teeth fish, is a fish class Perciformes fishes animal. Belonging to a wide range of octopus, the largest in the western Pacific and Indian Ocean, China’s coastal provinces can be seen, of which the highest output in the East China Sea. The octopus is a deep-sea fish that lives in the deep sea, and lives generally 40 to 50 meters below the water. By learning the knowledge of fluid pressure, we know that in the oceans, the greater the pressure of seawater as it travels to the bottom of the ocean. Therefore, in order to survive, the octopus living in the depths must keep the same pressure in the deep sea. In other words, the pressure of fish in the body is also great. When the octopus is caught by us to leave the water, due to the outside world
