This is the shocking moment terrified tourists had to flee a Benidorm beach after spotting a shark just yards from the shore.
Topless men - one of whom with a snorkel in hand - can be seen wading in the shallows before a large shark begins thrashing in the water nearby.
As they start thinking twice about taking a dip in the appetising sea, lifeguards desperately blow their whistles and encourage the holidaymakers to come back to safety.
But despite most swimmers leaving the water, some failed to get the message, the MailOnline reported.
Julie Roberts, 56, who was visiting Levante beach from Cheltenham, said a snorkeller was "just feet away" from the beast and didn't realise.
