When it comes to marine food, all kinds of seafood must come to mind. It seems that there is nothing in the sea that can't be eaten except poisonous. But among them, there is a kind of seafood that looks very ugly and even makes many people feel uncomfortable, which makes many people afraid to try, but they all praise him for what they have eaten, that is, barnacles, which are called regional delicacies.

Although barnacles are unsatisfactory in appearance, their taste is so tender that even if they are more troublesome to handle than crabs, many people will still pay for them, and their prices are much more expensive than ordinary shellfish, and the price is as high as more than 1, yuan a catty. Such an expensive barnacle, human beings are full of praise for its taste, but marine animals are not so kind to him, and even hate that she is regarded as a representative of bad luck by marine animals at the bottom of the sea. Every animal wants to get rid of him. Why?

barnacles, as an arthropod, have limestone shells marked by mollusks, because they are also standard parasitic animals. The growth of barnacles can be divided into three stages: nauplius larva, limited larva and adult. When he reaches the present world and picks up again, he must find a reliable attached object to settle down. Usually, they will choose a place where food is abundant and the surface of attached objects is wrinkled and uneven, so as to ensure that she can live a carefree life for the rest of her life. After barnacles were screened layer by layer, those large marine animals with few natural enemies became the first choice, including whales and turtles. On the internet, we often see whales and turtles carrying a large number of barnacles, which will make people's scalp numb every time we see them. Powerful whales and turtles will even die because of this small barnacle.

Although barnacles attached to these animals don't suck blood and eat meat like grasshoppers, which gives whales and turtles a happy way to die, when they are attached to their bodies, they will feel extremely itchy. Unbearable whales often jump out of the water and beat their bodies, so as to shatter barnacles, or even hit ships and shores with their bodies to scratch. These actions may make barnacles decline, but the white night marks attached to whales will never be eliminated. If barnacles are parasitic on turtles, turtles will not end up as handsome as whales, and even bring disaster. Compared with the swimming speed of Beijing fish, turtles can be said to be very slow, and barnacles usually don't fall off after being attached to the turtle shell, because there are many folds on the turtle shell, which is the ideal residence for barnacles, so barnacles on the turtle's back often grow very big. More and more barnacles are parasitic on turtles, which makes them bear more burdens, and the irregular barnacles also increase the swimming resistance of turtles, while the crushed returnees indirectly kill the murderer of Back Pain Lake because they can't swim to the surface in time for air.

barnacles not only do great harm to marine animals, but also parasitize the bottom of the ship, which increases the weight and resistance of the ship, and also destroys the protective layer of the transmission surface, affecting the speed of the ship and increasing fuel consumption, which has caused great trouble to marine operations. The reason why barnacles can be so firmly attached to objects is that the intersecting line of barnacles can secrete a liquid, and then it reaches its chassis through its suburban conduit, which serves as a natural adhesive to firmly fix itself and objects. But how barnacles secrete such a firm glue in the deep sea is still unknown. This magical protein on barnacles still needs to be studied by scientists, and it may be used as a very high-quality adhesive in human life one day. But for us now, barnacles may be just a delicious seafood, but for the marine animals persecuted by him, this is an annoying essence, and they may also pray. Let's eat more barnacles.
