The grey seal (Halichoerus grypus) is found only in the North Atlantic Ocean, the Baltic Sea and the Barents Sea. As one of the rarer seal species, its world population runs to just 350,000 to 400,000 individuals. About 40% of all grey seals live in UK waters – and about 90% of this number live off Scotland.
