Sharks are distinguished by their unusual teeth
''It looked really odd, and they kept on coming. All the while he wasn't losing his baby teeth.''
A schoolboy from Leeds, England has been nicknamed 'Jaws' by his classmates after forming a second set of teeth.
Zak Brown, eight, has seen his adult teeth start to grow behind his baby teeth, which means he's having to brush two sets of teeth at the moment.
His mum Claire, 38, explained: ''We thought something was a bit fishy when he got his first extra tooth through.
''It looked really odd, and they kept on coming. All the while he wasn't losing his baby teeth.''
The unusual situation is not easily discernible but have seen the youngster assume the Jaws nickname, which likens Zak to a shark.
