The BBC» Hundreds of sea potatoes cover Penzance beach
Hundreds of baseball-like sea creatures have washed up on a Cornish beach.
The small heart-shaped orbs were sea potatoes, a sea urchin that lives buried in sandy and muddy sea beds all around UK▸ coasts.
Rosie Hendricks was on the beach at Wherrytown in Penzance earlier with her daughter, sister and nephew when she spotted the "odd-looking" creatures.
Ms Hendricks, from Penzance, who had never seen anything like it before, said: "I wasn't sure what they were."
