The Greek word phállaina he came to Latin as ballaena, which in turn passed to Spanish as whale . The notion allows naming a animal Marine from the group of cetaceans It can measure more than thirty meters in length.
The whale is the largest animal in the world . It's about a mammal whose previous members are fins, it has a single horizontal fin and at the top of the head it has openings that allow it to expel the air.
In his jaw, the whales have beards (also called, like the animal, whales). These are flexible sheets located in a pair of parallel rows, which are similar to combs. Made of keratin, the whale whiskers allow the food to be filtered: cetaceans open their mouths when swimming so that the water enters and then, by means of the throat and language , they expel it again, leaving the food (krill, crustaceans, fish, etc.) retained.
Another peculiarity of whales is that the tail By its arrangement, it allows them to ascend to the surface with ease. This is very important since the whales must climb to breathe, having the possibility of being about an hour below the Water .
Whales live in their thirties and usually have only one calf each after a twelve month gestation. Usually these animals mate and have their young in seas warm and then migrate to colder waters to feed.
The Southern Right Whale , the greenland whale and the glacial free whale are some of the species existing whale.
In fiction, the figure of the whale has a rather important place, as well as that of other marine animals, such as the shark and octopus. In this case, one of the most important stories is without a doubt "Moby-dick", written by the American author Herman Melville and published in 1851. In broad strokes, the book tells the travels of Captain Ahab on board the Pequod, a ship whaler with whom he tried to accomplish his goal of catching a large white sperm whale.
Another species that has attracted the attention of the human being is the killer whale , which receives the nickname "killer whale", an expression that does not represent it at all. The killer whale is not a whale, but an odontocete cetacean that is part of Delphinidae, The family of oceanic dolphins; in fact, the gender to which they belong, called Orcinus, does not have any other species. It is the largest known dolphin in the world and has adapted to all oceans.
In 1984 a truly amazing discovery about whales and their abilities took place. A group of scientists from the National Marine Mammal Foundation of California, United States, began to notice certain strange sounds in the vicinity of the whale and dolphin tank, as if they were conversations between people, although they did not understand what What they said A few days later, everyone was speechless when a diver left the tank and asked who had called him: no human had spoken to him, but that it was one of the whales, called NOC, who had learned to imitate our sounds .
NOC was a white whale that went down in history for being the first to modify its sounding mechanisms to imitate the voice human It is important to understand that to carry out such a feat he had to lower several octaves and modify the pressure of his nasal tract, among other adjustments in his muscles, since the way of emitting whale sounds is very different from ours.
