Orca Aquatics

The largest of all animals, Whales are divided into two suborders: Baleen meaning whale baleen and toothed or toothed. Baleen whales are larger and have a baleen, a sieve like structure that filters the small fish they eat, the water. Toothed whales have teeth they use to eat fish and squid. They are also known for their ability to emit sounds and use them to navigate and forage, a phenomenon known as echolocation. Whales produce the loudest sounds amongst animals and often vocalize songs that may last as long as half an hour, possibly to communicate, descending track, locate prey or attract mates.

Very big and strong, the whales have no natural threats. They can weigh up to 150-200 tons. The body length often exceeds one hundred feet. Physics is fusiform and streamlined which allows it to swim freely. The neck vertebrae are united to ensure stability in the movement. Heart has four chambers and the body temperature is regulated like all warm-blooded mammals, the thick layer of fat under the skin acts as an insulator. He also serves as a reservoir of fat. The lungs are present instead of gills in fish, which means that the whales periodically to the surface to breathe, but can remain submerged for long periods. The vent is used for this purpose, the number two in the case of baleen and toothed whales for. The dorsal fin is often present. Sometimes small hindquarters are also observed, perhaps relics such as bones of the pelvis, is powered mainly by the fins or flukes.

Filed as predators, whales eat plankton as their main source of food, if large fish are often taken. Tons of krill are consumed daily by the blue whale, the largest creature in history. very intelligent animals, whales often live in groups called pods. These pods contain larger number of people in case of toothed whales that often travel and hunt together. Adult males are called bulls, cows and women. Every year whales migrate from the polar regions during winter, thousands of miles of travel in the seas. Speed is fastest in the event of Killer Whale or Orca, up to fifty kmh. During their activities, from whale show several blows Violation when they jump above the water surface, perhaps to get rid of parasites, play and socialize. Sometimes they can Skyhop is raising his head above water and look around. Then there Lobtailing, when whales stick their tail muscled out of the water, move it and tap the surface of the water, perhaps to send a warning through this noise.

The whales reproduce slowly, taking on average one year to give birth to offspring with only a difference of two to three years between births. Calves are born tail first to prevent them from drowning and begin to swim almost immediately. In case of blue whales, they weigh two tons at birth and gain two hundred pounds per day during the first year of life. Mother feeds them by squirting milk into their mouths, to avoid wastage. Bond is very strong between the calf and his mother, who protects and feeds up to one year of age. Life is forty to hundred years normally, but the oldest specimens of two hundred years have been recorded, making the whales the longest life of all mammals.
