Shocking pictures taken near Nairn, on the Moray Firth, show piles of stranded starfish, crabs and shellfish flung up along a large area of the shoreline in the aftermath of last weekend’s extreme weather.
The photographs were taken by Charlie Maciejewski, from Inverness, during a walk at Culbin Sands.
He said the washed-up creatures covered a 100m stretch of sand on the beach.
It is not known if any survived the stranding.
The weekend’s harsh weather, which saw winds of nearly 100mph and massive waves battering the coastline during Storm Arwen – the first official storm of the season – has been blamed.
The discovery comes following the death of more than 800 grey seal pups at a nature reserve in the Scottish Borders.
Hundreds of bodies were discovered in the water in a small area of bay at Pettico Wick, at St Abb’s Head, with many more washing up on the shore.
It is thought around 40 per cent of all the young in the colony perished during Storm Arwen, which struck at the height of pupping season for the species.
Rangers at the National Trust for Scotland, which manages the reserve, said the scale of the devastation was unprecedented.
Ciaran Hatsell, who works at the site, said the storm had left a "pretty grim scene" in its wake.
"To see piles of dead pups in the water – just bodies floating – was really hard to see,” he said.
