Whales are wonderful creatures. Their ancestors appeared on Earth 55 million years ago —that had been long before the first man came. It is well known fact that the average one weighs as much as 2,700 people and its heart size could be compared with of a car and weighs between 600 and 700 kg.

This animal is not a fish, but a mammal. It doesn't have the external ear - a traditional animal hearing. They can hear by means of the lower jaw, from which the sound comes to the middle and inner ear. The hearing is the most essential sense for the whale because it helps them to navigate under water, to communicate and to find and get food. Unfortunately, they have poor eyesight and no sense of smell at all. The tails are as individual as human fingerprints and that’s impossible to find two identical tails. Only human beings and whales can sing songs of all mammals.
Whales almost eat nothing most of the year and survive on the basis of the stored fat. However, all summer they feed non-stop, eating to three tons of food per day. Their diet mainly consists of algae and small crustaceans, but sometimes these mammals eat small fish. Not a lot of people know that these animals breathe oxygen and can drown while sleeping.

Киты - удивительные создания. Их предки появились на Земле 55 миллионов лет назад — это было задолго до прихода первого человека. Известно, что в среднем одна особь весит как 2700 человек и размер ее сердца можно сравнить с автомобиль, который весит от 600 до 700 кг.
Это животное-это является не рыбой, а млекопитающим. У него нет наружного уха – традиционного органа слуха у животного. Они могут слышать с нижней челюсти, от которой звук доходит до среднего и внутреннего уха. Слух является наиболее важным чувством для кита, потому что он им ориентироваться под водой, общаться и находить и добывать пищу.
К сожалению, у них слабое зрение и совсем нет обоняния. Хвосты так же уникальны, как и отпечатки человеческих пальцев и также невозможно найти двух одинаковых хвостов. Среди всех млекопитающих только люди и киты поют песни.
Киты почти ничего не едят большую часть года и выживают за счет накопленного жира. Однако все лето они питаются практически без остановки, едят до трех тонн пищи в день. Их рацион в основном состоит из водорослей и мелких рачков, но иногда эти млекопитающие едят мелких рыб. Не многие люди знают, что эти животные дышат кислородом и могут утонуть во время сна.
