Whales have those Are whales fish

Species of whales.

In Greece, the word "whale" stands for sea monster. We divide cetaceans into two groups:

Toothed cetaceans: toothed sea giants such as: sperm whales, orcas, dolphins, porpoises.

Baleen cetaceans: Whiskered whales. In fact, these whiskers are chamfered teeth that grow inside the mouth and are used to filter water and catch shrimp and other small animals that whales eat, and these teeth replace the teeth.

Depending on the species, baleen whales have two different methods of predation.

Degreasing: Beluga whales, like beluga, filter plankton as they swim slowly, with their mouths ajar and water flowing in from the commissure.

Feeding: When this whale approaches a large pool of shrimp on the bottom of the sea, it opens its mouth wide and swallows a large amount of water, which is packed into an extended, folded belly. When the mouth is closed, the whale's tongue reels in the water filtered by the whale's tooth plates. For example, blue whales can swallow 25,000 liters of water at a time.

Every year, some whales leave the food-rich polar oceans in search of warmer waters in order to have offspring. They travel thousands of kilometers over a period of several months in a very certain period. Every winter, many tourists sail thousands of miles to encounter them in the Hawaiian Sea and the Gulf of Mexico.

In the case of sperm whales, males are not allowed to migrate because there is not enough food for the squid in the breeding area.

Whales are not fish, so what is the largest fish in the world?The truth is revealed for you.

There are many species of whales, there are more than 80 species in the world, and there are more than 30 species in China's waters. They are generally divided into two categories. There are 11 species of baleen whales in the mouthThe other type has teeth in the mouth and is called toothed whales, with a total of more than 70 species.

Cetacea, which includes whales and dolphins, is the most adapted group of mammals to aquatic life, similar in appearance to fish, and is completely incapable of living on land, including some of the largest animals on Earth, and most of them are medium in size. The extant members of the cetacean all have fin-like forelimbs, and the hind limbs are completely vestigial, with a horizontal caudal fin at the end of the tail, and often a vertical dorsal fin in the north, and the nostrils move to the top of the head. The origin of cetaceans is relatively early, the Eocene mach-toothed whale basilosaurus (right) was already a large, fully adapted animal to marine life, and its semi-aquatic ancestors date back to an earlier era.

Cetaceans may have originated from similar ancestors of mesomammals, and are also closely related to artiodactyls, but they are very different from each other in terms of size and habits. The extant cetaceans can be divided into Odontoceti and Mysticeti, and the early types can be classified under the archaeoceti, and before the Paleoceta, there were some more primitive amphibious cetaceans, such as the Pakistani whale pakicetus, which show many similarities with mesomammals. The ancient cetacean suborder has teeth in its mouth and some remnants of its hind limbs, which have long been extinct; The toothed whale suborder includes most living cetaceans, which appeared in the Late Eocene, with teeth in the mouth and only one nostril; The suborder Baleen Whales have toothless and specialized baleen in their mouths, have two nostrils, are quite large, and include the largest animals in the world. If you think it's good, please adopt it as.

First of all, you have to get rid of the myth that whales, like dolphins, are not fish, they are mammals in the ocean.
