Angulas: Spanish delicacy priced at 30,000 zloty per kilogram

Angulas are larvae of the European eel — thin, pale creatures several centimeters long, sold in cans or jars. Once cheap food for poor fishermen, they are now considered one of Europe's most expensive delicacies, reaching prices of up to 30,000 zloty per kilogram. The species is threatened, putting the future of this delicacy in question.
