Males of dolphins have learned to give sponges for lovers

Australian and Swiss biologists found that males of humpback dolphins (Sousa sahulensis) bring potential sexual partners gifts – sponges of a certain kind. According to the researchers, except humans and some other primates, this behavior is not observed in wildlife. The corresponding article is published in Scientific Reports. Scientists for about ten years watched from the boats for the behavior of humpback dolphins of the north-eastern coast of Australia. They have repeatedly noticed that adult males of these mammals hold in their teeth primitive animals – marine sponges. Moreover, this occurs only in the presence of sexually mature females. One of the authors of the study described how, with him, the male humpbacked dolphin, after seeing the female with the cub, dived to the bottom, tore off the sponge from it, lifted it to the surface and threw it towards the female.
