A nine-metre long Minke whale has died after being washed up on a County Londonderry beach.
The dead whale was discovered at Magilligan Point, close to Magilligan Ranges on Tuesday.
A Ministry of Defence (MOD) spokesman said the MOD had taken "all appropriate actions" and had liaised with HM Coastguard and Limavady Borough Council.
Pádraig Whooley from the Irish Whale and Dolphin Group confirmed that the animal was a Minke whale and said they are frequently spotted in this part of the world.
"The Minke whale is Ireland's smallest and most commonly recorded whale species. In the past week there have been a series of sightings of Minke whales off the Bloody Foreland area of Donegal that have been reported to us.
"This species is also being reported with increased frequency off the Antrim and Down coast," he said.
Limavady Borough Council said their technical services staff were assisting the MOD and the Coastguard with the removal of the carcass, after fears that the corpse could drift into the Foyle estuary and become a shipping hazard.
