Dolphins set up societies to compete for partners

According to previous studies, only humans and gray dolphins have reached the level of complex male organization in their communities.

While female dolphins often do not live in a single group, the male dolphin community may remain unchanged for more than 15 years.

According to researchers, male gray dolphins in Shark Bay, Western Australia have sought to increase their female dolphins by dividing into 3 small groups and assigning specific tasks to each member.

The first group, consisting of 3 members, is on the mission to "attract" the dolphins to the birth. Dr. Richard Connor said this process will take more than a month.

Approximately 4 to 14 male dolphins of the second group will attack to 'rob' females from other herds or protect their herd from attacks.

The responsibility of the third group is to create a 'friendly relationship' with larger groups. They join the army of this large group and work together to protect their children from being robbed.

The researchers spent five years in Shark Bay, where a large number of gray dolphins gathered and recorded their activity. Dr. Richard Connor has been studying this species since the early 1980s. According to Connor, they must be 'extremely intelligent' animals that can organize society in this form.

Dr. Nichola Quick at the University of St Andrews (Scotland) said grasping how animals interact with their communities in nature is important to 'really understand their behavior '.
