Orcas are very social animals and usually live together - and they only survive because they "work together". It is a group that they hunt, play and rest. leader of the family is usually the eldest male. Other family members include females, offspring and close relatives. Members of the same group communicate both emitting sounds as through body language. A killer whale usually lives in the same group throughout your life. Can you imagine how your life would be if you lived forever with his mother, brothers, sisters, uncles, cousins, all in the same house? This only works well with killer whales - these mammals are very affectionate with each other. They develop very strong bonds with members of their own family.
What are the sounds that a killer whale emits?
Orcas emit various sounds. They may be quick clicks or whistles, squeaks and other noises. Some of the sounds emitted by them can be heard from miles away. Scientists believe that killer whales use sounds to signal to each other -. attract partners, to initiate a hunt and find prey Each group of orca whales has its own set of sounds, or its dialect. Related groups have also related dialects - and the group can understand the other. To find food, a killer whale uses echolocation. To do this, the first whale emits several "clicks" (sequence of whistles and clicks). The cliks spread across the water to hit an object or animal, like a fish. He then returns to the whale-shaped echo. Thus the whale can say where the shoal. And the whale can also tell you the size, shape, speed and direction of the school. 's orcas use echolocation to find fish and other smaller prey. But they do not always use echolocation to hunt. To find large prey, like seals, killer whales just use your eyes. Most toothed whales use echolocation at some point in their lives. Scientists believe that echolocation is a learned skill. How else orca whales find food? Normally orcas hunt in groups to "push" a school against the shore. Killer whales attacking not only fish, but also porpoises, seals, turtles, penguins and even other whales. Once caught the prey, the killer whale divide it with the other whales in their group. Sometimes a killer whale surprises his victim throwing ice on it. The seal or penguin slide on the ice and the whale uses his teeth to grab them. A killer whale has about 52 teeth, but she uses them to chew. Instead, the whale drags its meal into the water and swallows it whole. Killer whales are ferocious hunters and can capture most marine animals. It is virtually impossible to escape from the mouth of a hungry killer whale -., And is exactly why she earned that nickname Killer whales usually stay still or traveling long distances? Some killer whales stay in one place. Other travel great distances. Everything depends on the type of group in which they operate. A very common type of group is called a transient. Whales that live in these groups travel great distances. These groups are generally quite small, with only seven members. Transient groups of whales usually feed on large marine animals such as seals and porpoises. Some transient groups arrive to attack even other whales. residents groups often do not move much and are easily observed. In fact, much of what we know today about killer whales come from the study of these groups. Residents groups may have between 5 and 25 members of this group and whales feed mainly on fish. When a group gets too big, the female and her offspring can leave and start a new group. How is the life of a puppy Whale? Childbirth is complicated both for the puppy and for the mother. Like most mammals, whales do not lay eggs. Females give birth to calf underwater. When the hour of birth, the mother floats toward the surface of the water. Usually the first part of the baby leaves the mother's tail. The head of the puppy is the last part that appears. But due to not having air in your lungs, the newborn puppy needs to get quickly to the surface. soon as the baby is born, the mother pushes the puppy toward the water surface. There, the cub fills your lungs with air. Only then he can return to his mother and start sucking. The cub breast milk directly from the mother's nipples. Killer whales are good mothers? Killer whales are excellent mothers. They care for their young for at least one year. During this period, the pups depend on their mothers to feed and protect themselves. A baby orca whale ever anything beside his mother. The flow of water over the body of the mother helps the puppy to move so that he need not spend much energy. Sometimes a mother needs to go out in search of food. It leaves your puppy with other adult females. These females protect the baby sharks and other whales, as well as play with him.
