Greek tragedy: the rare seals hiding in caves to escape tourists

Greece is hoping that protected areas will help keep daytrippers away and allow vulnerable monk seals to return to their island habitats

Deep in a sea cave in Greece’s northern Sporades, a bulky shape moves in the gloom. Someone on the boat bobbing quietly on the water close by passes round a pair of binoculars and yes! – there it is. It’s a huge Mediterranean monk seal, one of the world’s rarest marine mammals , which at up to 2.8 metres and over 300kg (660lbs), is also one of the world’s largest types of seal.

Piperi, where the seal has come ashore, is a strictly guarded island in the National Marine Park of Alonissos and Northern Sporades, Greece’s largest marine protected area (MPA) and a critical breeding habitat for the seals. Only researchers are allowed within three miles of its shores, with permission from the government’s Natural Environment and Climate Change Agency.
