日常生活中经常提到一些鱼,其实从动物分类上说它们并不是鱼,是名不副实的“鱼”。下面介绍几种我们身边的“假鱼”:墨鱼,又名乌贼,属软体动物头足类,生活在海里,体呈袋形,头部发达,周围有10个腕足,眼大,躯干背部内有石灰质骨,介壳退化,体内有墨囊,遇到敌害即放出墨汁逃走。乌贼可供食用,墨汁可制颜料,骨供药用,中药称“海螵蛸”。 In the daily life, some fish are often mentioned. In fact, they are not fish from animal classifications. They are unworthy of “fish”. Here are some of the “pseudofishes” that are around us: squid, also known as squid, is a mollusk cephalopod, lives in the sea, has a pocket-like shape, has a well-developed head, and has 10 brachiopods, large eyes, and a torso around it. There are calcareous bones in the back, the shell is degraded, and the body has ink sacs. In the face of predators, they release ink to escape. Squid can be eaten, ink can be made of pigment, bone for medicinal purposes, Chinese medicine called “sea lice ”.
