Rare whale vomit may have been found at Porth Dafarch
An Anglesey man may have found a rare substance vomited by whales that could be worth "tens of thousands of US dollars" a kilo.
Andrew Hughes found what he thinks is ambergris, produced in the intestines of sperm whales, at Porth Dafarch near Trearddur Bay.
The yellow and black lump substance is used to produce perfume.
