Males also have longer noses than females. The male nose is so distinctive that the gray seal’s scientific name, Halichoerus grypus, means "hooked-nosed pig of the sea." Gray seal pups have white fur known as lanugo. This white fur helps absorb sunlight and trap heat to keep the pups warm. The lanugo is also related to their evolutionary history with other ice-breeding seals. Gray seals breed on ice or sandy beaches in parts of Canada (Gulf of St. Lawrence, Sable Island, Nova Scotia) and on sandy or rocky beaches or islands in the U.S., and in parts of the Baltic Sea. Pups shed their lanugo when they are about 3 weeks old.
