An angry dolphin is suspected of biting countless swimmers in the Japanese town of Fukui, prompting authorities to issue a warning.
The mammal has bitten at least 10 people, forcing the Fukui municipal government to set up a device that emits ultrasonic frequencies to prevent it from approaching the coast.
Fukui Prefectural Police has also warned swimmers not to pet the animal and warned of “possibly serious injuries”.
“Dolphins are often thought of as cute, but if you approach wild dolphins carelessly, you can get bitten and injured,” reads a Twitter post.
“If you see one, don’t go near it.”
Police went on to cite a case of a man bitten in his hand on Sunday.
An official from the tourism promotion department told AFP they believe the attacks are the work of a single animal, which was first seen on another beach in April.

“We understand that there are certain parts of the body where dolphins don’t like to be touched, such as the tip of its nose and its dorsal fin,” Masaki Yasui said.
“We encourage visitors to view the dolphin from a distance if they come across it.”
