Dead sperm whales are seen washed up on a beach on Texel Island, The Netherlands, January 13, 2016. The five sperm whales that beached on the Dutch lsland of Texel on Tuesday have died overnight, Dutch media reported. It is extremely unusual for so many whales to be in Dutch waters, a spokesman for the Ecomare marine centre told local paper Noordhollands Dagblad. Efforts to get the whales back into open water on Tuesday evening failed and rescuers finally withdrew from the beach at around midnight. The area of beach where the whales are has been closed to the public, to minimise the distress to the animals. (Photo by Cris Toala Olivares/Reuters)
