Seeing the whale's body covered with very dense barnacles always makes us feel numb on the scalp, and we especially want to use a knife to help him dig out all the barnacles on his body. When the barnacle is a larvae, it will swim to the surface of the whale's body and use its head and back plate to burrow into the whale's skin. After success, the barnacle's body will begin to secrete The very strong glue sticks to the surface of the whale and while it grows, it uses its back plate to continue to penetrate into the lower skin of the whale. Finally, the barnacles that invade the skin will have their back plate downward, or It is drawn inward and completely attached to the surface of the whale, integrating with its skin. If the barnacle is pulled off by force, a big scar will be left on the whale's body. As the whale itself grows and its skin metabolizes, the barnacles must continue to extend downward, and its back plate will also increase in size at the same time, otherwise it is likely to be removed from the whale's body. It was very uncomfortable for the whale to have it fall off its body. A creature is constantly embedded in its own skin, and it keeps growing. It must be extremely itchy. For example, we see a whale jumping out of the water on TV, and then slamming back into the water, causing a lot of waves. In fact, it is not playing, but just tickling itself. Large whales can remove barnacles from their surfaces by jumping out of the water and diving into the deep sea. Whales can get rid of some barnacles by jumping up and slapping the water, causing collisions and frictions between similar species, and friction with the sand and stones on the seabed. Some whales will also leave marks of barnacles on their bodies. For some large whales, there is another method. For example, sperm whales are very large, weighing about 20 tons, and are not particularly fast. It is the most ideal target for barnacle parasitism, but in fact, the sperm whale is very clean with very few barnacles attached to it. This is because it dives into the deep sea of ??about 3,000 meters every day. The sperm whale is the most special. Their structure allows them to easily handle very large water pressures; however, barnacle-like bodies may not be able to withstand such large pressures. These amputated animals are removed when the sperm whales are done phasing.
