A leopard seal on ice

This is a colour photograph of a leopard seal ('Hydrurga leptonyx') lying on an ice floe. The seal is long and sinuous, and has a small head and a dark grey dorsal surface with a lighter grey underbelly. The seal has recently eaten, and blood from its kill can be seen on the ice.
