Some interactions are unilateral, but many are cooperatives. It is the playful and social nature of marine life working.
The interactions between dolphin e whales with fin are often mutually playful, instead of unilateral.
Scientists have analyzed 199 distinct encounters in 17 places worldwide, captured through public submissions, tour operators and scientific filming, involving 19 species of whales and dolphins.
Revealed that approximately a quarter of the interactions were mutually engaging.
As jubart They stressed, showing positive answers in about one third of the meetings, including rolling, belly presentation and deliberate approach to dolphins-behaviors normally associated with socialization or court.
Co -author Olivia Crawley who, such as dolphins, “walking towing” and playing the whales, suggests complex social behaviors, not harassment. “Documenting these interactions helps us understand social structures and the playful behaviors of marine mammals,” he said.
The study registered 425 barbatan whales-especially jubarts, followed by E-Fin Whales gray whales-and about 1,570 dolphins, predominantly rolling dolphins, ordinary dolphins and dolphins Pacific Wide-Sided. Interactions were observed Between adults and offspring, sometimes with offspring of both species present.
The specific answers of the species varied: the jubarts used pectoral fins to interact with dolphins, the gray whales rolled, and the occasionally beating the pectoral fins. Aggressive behaviors were rare. Suction chambers filming have even shown dolphins to follow jubarts to the bottom of the sea, keeping close and apparent approaches.
Although some interactions are unilateral, many are cooperatives, highlighting the playful and social nature of marine life.
