While visiting Yankee Harbour, a natural harbour on the South-side of Greenwich Island in the South Shetlands, we witnessed the harsh reality of life in the Antarctic. A Leopard seal (Hydrurga leptonyx) in hunting mood, was chasing Gentoo penguins, until it succeeded catching an individual and proceeding to eat it, smashing it against the surface, getting rid of the tough skin and feathers, swallowing the meat and fat in small bits.
