Footage of a dead dolphin washed up on Portreath Beach in Cornwall, UK with its head and fin apparently bitten off. <br /><br />The video, filmed on Sunday, shows the animal with bite marks all over its body, which has led to speculation that a large shark might be frequenting British waters. <br /><br />The filmer later wrote online: "We woke up ... and noticed an animal on the beach not moving so went to have a look to see if we could save it but soon realised it was a baby dolphin that had been attacked by something huge. <br /><br />"It's fin and head had been bitten off and there were puncture marks about two inches long."<br /><br />"Wonder what is out there in the sea that did this?" she continued.
