Anglesey beach find could be whale ambergris

An Anglesey man has found what he believes to be a rare substance vomited by whales.

Andrew Hughes found what he thinks is ambergris, produced in the intestines of sperm whales, as he looked for fishing bait at Porth Dafarch near Trearddur Bay.

If it is the real thing it could be worth "tens of thousands of US dollars" a kilo, depending on the quality.
