:-) надо выбрать животное и дать ему характеристику(я выбрала дельфина)заранее : -): -): -): -)

Some of the most sociable and friendly members of the animal world - members of the family Delphinidae. These include dolphins and porpoises. Their mother feeds milk, so dolphins are mammals. They - warm-blooded. They have sharp teeth, and their head ends mouth, like a bird's beak. The main food of dolphins - fish, shellfish and small animals. 

Conventional dolphins have a length of about 1.6 meters. Head slightly protrude. At Dolphin great growth with 80-100 teeth. Top Dolphins have a black or gray in color, and the belly they white with black fins. A porpoise that lives in all latitudes from Greenland to North Africa - one of the most peaceful dolphins. In search of food, it can even go in the river and tear fishing nets. 

But fish it eats crustaceans and even algae. So she tries to stay in the shallow water, where she has many food. The name "dolphin" is related to the ancient Greek legend. According to her the god Apollo, becoming a dolphin, the settlers have a way to Delphi, which was founded by the famous Temple of Apollo. The name "porpoise" comes from the Latin. 

I enjoy these friendly animals - dolphins. 

Dolphins are amazing creatures. They live under the water, they breathe air use to breath special hole at the top of the head. Like humans, Dolphin can drown if his lungs will get 2 tablespoons water.
Dolphins look like fish, but actually mammals. Dolphins have always help each other and never abandon brothers in trouble.
Дельфины – удивительные существа.  Они живут под водой, но дышат воздухом, используют для дыхания специальное отверстие вверху головы.  Как и человек, дельфин может утонуть, если в его легкие попадет 2 столовые ложки воды.   Дельфины выглядят, как рыбы, но на самом деле – млекопитающие.  Дельфины всегда друг другу и никогда не бросают собратьев в беде.
