Dolphins wave weed to attract a mate

While men might try flowers, smart clothes or cars to impress the opposite sex, male Amazon river dolphins carry weed.
Object-carrying has been reported throughout the dolphin’s range in Brazil, Venezuela and Bolivia, but what had been thought to be play behaviour now appears – exceptionally among mammals – to have a sexual function.
Tony Martin of the British Antarctic Survey in Cambridge, UK, and Vera da Silva of the National Institute of Amazonian Research in Amazonas, Brazil, have studied the dolphins for three years in the Brazilian Amazon and are now convinced it is a sexual display. Only humans and chimps do anything remotely similar, says Martin. “It’s so unusual that many of my colleagues were sceptical when I first suggested the idea, but now I think the evidence is overwhelming,” he says.
