As the days gradually get warmer, increasing numbers are heading down to their local beaches and spotting all kinds of wildlife.
And recently, people in Pembrokeshire have been seeing strange spikes along their coastline. Resident Lee Murray spotted the spikes whilst walking between Wiseman's Bridge and Saundersfoot. Lee and other beach goers have taken to social media to ask about the spikes, which they presumed to belong to some kind of crustacean.
The spikes actually belong to the masked crab. The name 'masked crab' comes from the patterns on the outer shell which sometimes look like a human face. This crab is mostly found around the south and west of the British Isles, but there are smaller isolated populations across the country and throughout European waters.
