Harp seals have a very healthy appetite. Because fishermen have always seen them as competitors, they have been hunted since earlier days. The fur of a newly born pup was also very desirable. It is presently forbidden to hunt these very young seals. Harp seals are still hunted in Canada and Norway, but the animals must be older than three weeks. Although harp seals are closely related to harbour seals, they don't live in the North Sea. A lost seal is only occasionally spotted along the Dutch coast.
