Scientists have discovered a unique feature of dolphins to schedule hunting

A 9-year study identified the unusual behavior of bottlenose dolphins (Tursiops truncatus) living off the coast of Slovenia. Within the limits of one population for the duration of the hunt, they are divided into two groups that forage in the same place, but at different times. In other words, they are able to draw up a hunting schedule and coordinate it with other members of the pack.

To identify dolphins, scientists used photographs of their dorsal fins. In the field of view of the researchers were 38 animals. Each of their appearances was carefully recorded in time. There were 19 and 13 individuals in two groups, respectively, 6 more dolphins made up the third group.

The first group of 19 individuals hunted constantly, following the fishing vessels in the Gulf of Trieste. Dolphins from the second, smaller group, on the other hand, have never been seen near fishermen. Although both groups hunted in approximately the same area, they never "overlapped" in time. So, the first group "hunted" from about 7 am to 1 pm, while the other - from 6 pm to 9 pm.

According to scientists, this behavior of dolphins prevents internal conflicts within the community and reduces competition for food. The exact mechanism by which these unusually intelligent animals agree on their schedules remains to be seen.
