whales and their feeding

The whales feed in different ways, depending on the species. Some have teeth as white whales, which feed on large prey such as the giant squid, which caught the traveling several kilometers under water, after detecting their sonar in utter darkness.
Although Valdés Peninsula area is the area of supply of this kind, you can register any such activity at the end of the season (October / November), before starting the migration of animals to the real areas of food, where they are abundant pockets of krill. In the area of Peninsula Valdes, is common with large concentrations of cross-tenóforos high protein content, and squid. The whale swallows tons of sea water, which is then removed from the mouth, filtering with those beards. Large amounts of food are trapped, being collected by his enormous tongue.

The female whales are always larger than males (12/14 m) and usually live in pairs or small groups, and breed in warm temperate seas. Females are suitable for breeding when they reach the 13/16 meter (3 / 4 years). The baby whales are able to swim at birth. The whale calves, puppies, born with a length of 5.5 m and 3.5 cm aproximdamente growing daily for the first two months, reaching a maximum weight for the species of 30/40 tons. They come to take up to 200 liters of milk a day, that milk contains a high percentage of fat. Unlike other mammals, including humans, breastfeeding is not unconscious, quite the contrary, the animal on its mother's mouth and this "eject" a dash of milk fat may reach about 50 kg. diarios.El gestation period for most species varies from one year to 16 months and all are characterized by a long period of careful breeding and feeding, about a year. Finally one of the most remarkable features of some cetaceans is their extraordinary ability to echolocation which is the location of an object by emitting and receiving sound. Some whales are solitary, others live in groups (schools). Large groups are each made up of small groups or units, each with a different function. The variety of habitats in which they live and their system of organization are witnessing the complete invasion and adaptation of the marine mammals. (Mother). The playability of cetaceans is relatively low compared with other mammals.
