Cheerful surfing. Scientists have finally found out why dolphins like to ride on waves (video)

For many years, scientists believed that such behavior of cetaceans, which is also observed in marine pigs, is actually a game. But a new study suggests that everything is a little different.

According to the co -author of the study, associate professor of the Department of Biology of Texas University, Dr.

Dara Orbach, they came to the conclusion that in fact dolphins in this way save energy, rolling on waves, which otherwise would be spent on swimming. The authors of the study also recognize that receiving transport benefits and conservation of energy does not mean that mammals are not fun. According to orbach, the game and energy efficiency are not necessarily mutual. In other words, the wave riding can be effective and fun for dolphins.

During the study, scientists surveyed dark dolphins (Lagenorhynchus obcurus) off the coast of New Zealand, using a drone for accidental frames while traveling cetaceans between feeding and coastal waters. Researchers acknowledge that the task was not simple because dolphins are extremely fast animals. According to another co -author of the study, Dr. Lorenzo Fiori, as soon as scientists began to record dolphins, they followed the animal.

The scientists then viewed the filled material at low speed, counting every time the breathing opened and closed to indicate the breathing frequency of the animal. The team found that as dolphins increase their speed or energy consumption, they take more breaths, increasing the respiratory rate. But at the time of riding, the respiratory rate of animals was reduced, indicating that they use waves to save energy.
