There has been a steep increase in sightings of blue sharks off Spanish beaches this year. Yesterday, locals and holidaymakers at Praia Beach in Espinho, Portugal cleared the sea.
Footage showed two blue sharks moving through shallow waters near a beach in Portbou, Catalonia, at around noon on July 16. Swimmers quickly scrambled to flee the water.
In the video, locals and tourists can be heard warning their children to get out of the water in La Antilla, Spain, as others ran up and down the beach fearing a shark was about to attack.
