Razor clams live buried in sand at low tide, identified by small keyhole-shaped holes.
They are often harvested by the pouring of salt into these holes to force them out.
They washed up at Mablethorpe on the Lincolnshire coast.
A video by National Coastwatch revealed the scene – and the crunching sound the shells made underfoot, as reported by What’s The Jam.
The creatures are so named as they resemble old-fashioned barbers’ razors and have sharp edges.

Viewers were shocked at the number of clams.
Mary Birt said: “Makes you wonder where they all come from.”
Another asked: “What’s killing them off?”

Julie Montgomery said: “Maybe dredging Humber estuary again caused it?

“We had large numbers of cuttlefish previously.”
And Frances Richards added: “Love hearing this, makes me feel as if I’m there.”

Earlier this week, Studland Bay in Dorset was compared to a scene from Stranger Things after being invaded by strange-looking, one-footed creatures.
Hundreds of rare otter shell clams were scattered along the shore – an eerie sight recalling Lovecraftian beings from the spooky Netflix series.
