The velvet swimming crabs - also called devil crabs - are thought to be victims of Britain's coldest December in 120 years, which left sea temperatures much lower than average.

More than 40,000 of the crabs - Britain's largest swimming crab - are littering beaches around Thanet, along with smaller numbers of whelks, sponges and anemones.
Coastal warden Tony Sykes said: 'We suspect that climate change and warmer weather has lured the crabs towards the shoreline.
'They could also be attracted to these waters looking for kelp, to feed on.
'We believe the sudden temperature drop causes the crabs to suffer from hypothermia and die.'
It is the second year in a row that icy temperatures have killed sea creatures in such large numbers.
