Going to the beach for fishing, passing by a huge sand pit, a strange smell came! Wow, what is this, a big fish? It’s too big! Filling the entire sand pit, it feels like the mountains and plains are all over the place!
It turned out that this was a big whale fishing at the seaside. I guess I have seen many whales stranded, but this is the first time I have seen such a big whale!
Moreover, how did such a big whale get into this bunker? Is it too late to go at low tide, or suicide?
Some people say that this is a blue whale, the largest creature on earth. In recent years, there have been many accidents of large whale strandings, but the reason is still unclear. It is often encountered when fishing at the beach.
It belongs to the phylum Chordate, the subphylum of vertebrates, the class of mammals, and the subclass of eutheria, including about 98 species of viviparous mammals living in the ocean and rivers. There are more than 30 species in Chinese waters. The definition of “whale” itself is rather vague, and cetaceans can include all cetaceans, as well as cetaceans of specific families. Cetaceans also include dolphins, killer whales and pilot whales belonging to the family Delphinidae. Cetaceans are divided into two suborders: baleen whales (Mysticeti) and toothed whales (Odontoceti). There are few species of baleen whales, but they are huge in size. The smallest known species is more than 6 meters long, and the world’s largest animal, the blue whale, also belongs to it. The body shape of toothed whales is quite different. The smallest species is only about 3 decimeters in length, and the largest, the sperm whale, is more than 20 meters. In terms of weight, the largest whale currently weighs 160,000 kilograms, and the smallest weighs 2,000 kilograms. Whales are not fish. Whales are mammals.
