Did you know that the dolphin brain volume and mass are superior to those of the human brain? Thus, a mature common dolphin brain weighs about 1,600 g while the human brain weighs about 1,375 g. Dolphins are extremely curious and eager to learn new things and have an increased ability to understand what is happening around them. Here are other interesting things about dolphins:

"1* Dolphins are mammals feeding their chickens with milk. And, moreover, at birth, the dolphin female is guarded and assisted by another female.

2 The Dolphins can last for about 15 minutes under water because they have to get out of the air.

3 They are very sociable and they like to live in a group and cooperate to look for food together.

4The largest species of dolphin is orca, also called "killer whale."

It reaches up to 6.1 m long. Orca is often confused with a whale because of its large size but is part of the cetacean family like dolphins.

5 Being mammals, dolphins have warm blood and a body temperature of about 36 ° C.

To be able to maintain a constant body temperature, the dolphins are covered with a layer of fat right under the skin.

6 They have a complex communication system and use ultrasound for guidance, and can receive messages from distances for tens of kilometers.

Each dolphin has its own "signature signature", through which it is recognized by others.

7 In general, they can swim at a speed of 5 to 12 km per hour but in dangerous situations some species can reach a speed of 30 km / h.

8 Dolphins also have sex outside the fertile period for pleasure and for strengthening relationships.

Until this behavior was discovered, sex for pleasure was considered to be specific to humans only.

9 We never fall asleep because the brain's hemispheres come to rest in a row.

10 A dolphin lives between 25-35 years and reaches sexual maturity at 5-10 years for the female and 9-13 years for the male.
