Dolphins and whales

Dolphins

Sweet with children and strong enough to defeat sharks. More recently, reports of intense friendship between dolphins and children were seen and documented.
For a dolphin, trying to talk with our frequency and speed, the result would be this: we speak VERY slowly.Cause dolphins use a language that is 10 times faster than our speech.

The only things that a dolphin does is eat large quantities of fish and play.
It's speaker, friendly, loving with their owners, heroic, able to save drowned pushing them to the beach.

Orca.

Why killer whale?

Because of food of warm-blooded animals and is very agile, the orca received this unfortunate name of whale-killing. Many people fear their ferocity, but that does not make sense. The orca capture and kill its prey to feed themselves and survive.
But the man is not included in their diet. In the world has not been proven officially cases of attacks by killer whales to humans.
The orca can be found throughout the world . With more frequency in waters cooler than in tropical or subtropical waters. Remaining on the surface of the water between 5 to 15 minutes, rising at intervals to breathe.

Blue Whale

The blue whale is probably the largest animal that already existed on the face of the Earth.

The head of a blue whale is so great that fifty people could support themselves in their tongue.

A newly born blue whale weighs more than an elephant adult and has about 7.6 meters in length. During its first seven months of life, babies of whale blue take approximately 380 liters of milk every day. Baby-blue whales, gaining weight rapidly, 91 kg every 24 hours.
The heavier already heavy blue whale is a female that weighed almost 390 tons. Despite being mammals, whales not breastfeeding their pups by tits. The milk of the whale is so greasy that it loose in the water, where the offspring sucks, since water and fat do not mix.
