Australia - Grey seals discovered clapping underwater to communicate
Marine mammals like whales and seals usually communicate vocally using calls and whistles.
But now a Monash University-led international study has discovered that wild grey seals can also clap their flippers underwater during the breeding season, as a show of strength that warns off competitors and advertises to potential mates.
This is the first time a seal has been seen clapping completely underwater using its front flippers.
"The discovery of 'clapping seals' might not seem that surprising, after all, they're famous for clapping in zoos and aquaria," said lead study author Dr. David Hocking from Monash University's School of Biological Sciences.
