#MarineWildlife - In a week that saw the Isle of Man's first sighting of a humpback whale for three years, BBC News reports on the strange discovery of a rare species of dolphin two miles inland from the shore in Co Donegal.

The carcass of an Atlantic white-sided dolphin was found on a hillside near Meenbanad with head injuries - but no one knows how it got there.

Pádraig Whooley of the Irish Whale and Dolphin Group (IWDG) said it's most likely that someone found the dead cetacean on the beach and took it to the hillside to decay so that its skeleton could later be retrieved.

The dolphin is thought to be one of a pod that beached at Traigheanna Bay in Dungloe on 21 June. The species is a rare sight in Irish coastal waters, said Whooley, because they tend to feed much further out at sea.

In other stranding news, the IWDG reports that a bottlenose dolphin who live stranded at Beal in Co Kerry last summer has been recorded in the Shannon Estuary with her calf on a number of occasions this month and last.

The Shannon Dolphin and Wildlife Foundation has more on the sightings of the dolphin they now call Sandy Salmon.
