Roe deer occupy the countryside in growing numbers, and large-antlered red deer can be found in the sparse woodlands of Jutland. Denmark is also home to smaller mammals, such as polecats, hares and hedgehogs. Approximately 400 bird species inhabit Denmark and about 160 of those breed in the country. Large marine mammals include healthy populations of Harbour porpoise, growing numbers of pinnipeds and occasional visits of large whales, including blue whales and orcas. Cod, herring and plaice are abundant culinary fish in Danish waters and form the basis for a large fishing industry.
