Finally, conservationists have created a whale wash to clean skin parasites from whales! Well... of course you realized that it's all a hat)) No one created a whale wash, it's all fun with a neural network. But what kind of parasites can be found on whales? A lot of people, actually. For example, whale lice. Whale lice are crustaceans from the order bokoplavov. They live on the skin of cetaceans (especially in the area of the anal and genital openings) and feed on their tissues — with severe infection, this leads to the formation of ulcers reaching the layer of subcutaneous fat. In warm waters, mixins and leeches cling to whales. To get a better grip, the mixin is even tied in a knot. Voracious leeches are capable of swallowing meat 8 times their own weight in 7 hours. Balanus can also be found on whales. These are barnacles, but they do not eat their host, but use it as a means of transportation. An adult balanus sits in a lime shell that is firmly attached to something. The plates of this shell can move apart due to the action of special muscles. And the crustacean itself lies on its back at the bottom of the house, sticks its limbs out between the open plates and waves them, driving water with food particles into the house. Up to 400 kg of such passengers can sit on one humpback whale. Sea ducks also settle on whales. They are relatives of balanuses, but differ from them in the presence of a rather long stalk, which the animal attaches to and a larger size of the calcareous shell. So maybe whale washes are needed after all))
