A dolphin attacking swimmers in Japan is probably lonely and sexually frustrated, experts say.

At least 18 people have been injured in dolphin attacks in Fukui prefecture this year in what is becoming an annual occurrence in the region. Most of the injuries are minor bites, but some beachgoers have suffered broken bones since the attacks started in 2022.
