The researchers first recorded case of the friendship between dolphins and sperm whales cub

German biologist managed to shoot in the Azores unusual behavior of a group of sperm whales, which took in his company bottlenose dolphin with a defect of the spine.

The group of sperm whales Physeter macrocephalus was discovered by scientists in the 15-20 km from the island of Pico in the Azores included. Among several adult sperm whales and their young, researchers saw an adult bottlenose dolphin Tursiops truncatus with the curvature of the spine. He played with dangerous predators, just as do the young dolphins and sperm whales. The latter, according to the authors, was clearly against such a neighborhood and reciprocated.



Such interspecies communication is quite rare, and between sperm whales and bottlenose dolphins recorded for the first time. It is very unusual because the flock of dolphins sperm whales may attack and chase their young.

Scientists believe it unlikely that the group of sperm whales dolphins resulted in the search for protection from predators (they are rare in these waters). Rather, because of a physical defect caused by the inability to swim quickly, the animal it could not become part of the flock of his relatives and found alternative "society».

Dolphins are known for the complexity of their social organization. Recently, another group of scientists have discovered a group of bottlenose dolphins among mutual support called the researchers' dolphin mafia. " Collisions of such groups sometimes lead to a mass brawl.
