Grey seals (Halichoerus grypus) on haul out in fishing harbour with ferry in the background, Lerwick, Shetland Isles, Scotland, UK, June 2010. Photographer quote: 'These seals line up to take advantage of scraps of fish from a local processing plant - I know this because I had to crawl through the gunge!' Did you know? Like most predators, grey seals are opportunists here loitering around a fish processing factory hoping for handouts.
