10 amazing animals with advanced social life

Maybe they can't print a message in 140 characters, and generally communicate in social networks is not in condition, but nevertheless a social life of some animals is impressive.

1. The cows in the herd are smarter than cows-singles

Everyone knows that cows, for the most part, live in herds, but few could have imagined that the society is each other affects their ingenuity the most beneficial way. In order to prove this, the researchers collected the calves and tested them for the ability to “change skill”. First, they learned to associate the white square with availability of food and black its absence. Once these associations firmly fixed in their head, the colors changed, and calves had to be retrained to get to the good stuff. Indeed, calves that lived with other calves, handled the training faster than isolated from society like themselves.

2. Female mule deer – the world's best babysitter

When a female mule deer out to walk around and nibble the grass, her cubs taken to look after other female. And if suddenly there was a predator, then this other female will rush to defend all nearby cubs as their own, even if their parents belong to quite another species of deer.

3. Coyotes and badgers combined for hunting

Sometimes a completely different animal, where it's easier to make enemies than friends, come together to achieve a common goal. For example, a team of coyotes and badgers and leaves the prey no chance. If hunting is on the surface – that the prey chase the coyotes, if she manages to hide in some hole – it is taken for badgers. Prairie dog and squirrel, which was targeted a team – virtually doomed.

4. Orcas teach their friends to fish

Black killer whale is able to learn different tricks and stunts to each other. The staff of one of the largest marine parks were able to see how one of the orcas chewed the fish was giving her, but not swallow, and spit out and waited for it to “bite” some kind of bird. Unsuspecting Seagull sat on the water to eat the treats, and the next moment was in the mouth of a whale. That in itself is amazing. But even more amazing that this whale taught the trick with the chewed fish, at least three of their relatives.

5. Rhesus monkeys can starve themselves to protect other

In 1964, the researchers placed two rhesus monkeys in a terrible situation: if one monkey pulled the chain, you could get to the food, but at the same time, another monkey received a painful jolt of electricity. Once the monkey realized what was happening, then refused to pull the chain and sat hunger 12 days – that is, literally, voluntarily starved himself to death, not to cause suffering to their neighbors. The conclusion is clear: monkeys are capable of compassion and people should learn from them.

6. Dolphins have a joint “banquets”

In the ocean up to six dolphins often form teams that are driven schools of fish in one dense lump. Once they succeed, they line up to create a wave and drive away the fish to the shore (where it is easier for her to hunt) and have a feast.

7. Elephants talk to each other (sometimes with the help of secret signals)

Elephants not only communicate with each other – sometimes they use those sounds that the human ear is not able to capture. The researchers studied the behavior of elephants in the wild, found that elephants use more than 70 vocal tones and over 160 visual and tactile signals, expressions and gestures. These signals can convey such messages as “Come” or “Help, I'm lost”. Last post elephants often communicate at low frequencies, and other animals can pick up signals several kilometers away and rush to help.

8. Cuttlefish can solve several tasks at the same time

For us humans to change in different social situations is perfectly normal. We show one side of his personality, the boss and the other friends and family. But cuttlefish can be different at the same time different parts of her body are colored differently in order to perform multiple tasks at once. For example, one part of it can attract the male for mating, the other – to hide, to remain undetected by predators. They can even use certain colors to state a claim upon social dominance in certain situations. This means that the cuttlefish has a no notion of hierarchy and social structure.

9. The spiders know that millions of legs are better than eight

What could be worse than the thought of thousands (or even millions) of spiders that have joined together to achieve a common goal. Certain “social” types of spiders come together to weave a giant web in which to catch much more prey. In 2007, Texas Park are the spiders spun a web covering more than 150 sq. m. On the “project” worked about 12 spider families.

10. Penguins doing synchronised movements to warm up

It is known that Emperor penguins tend to huddle each other to keep warm. But that's not all – from time to time they do special synchronized movements to accumulate heat. Once every 30-60 seconds, all penguins in the same row move 5-10 cm in the same direction. Then the same movement is repeated the penguins in the next row, and so on. Researchers believe that constant movement helps to keep the density of penguins in the group and promotes better blood circulation in animals.
