A lump of whale vomit found by a dog walker on an Anglesey beach has sold at auction for £11,000.

Ambergris is a wax-like substance found in the the intestine of a sperm whale and it's a very rare and sought-after ingredient in the perfume industry.

The 1.1kg (2.4lb) chunk was bought by an anonymous telephone bidder in France.
