Since the beginning of August, the beaches of Cornwall, a seaside resort in south-west England, have been invaded by a very special visitor.
Thousands of spider crabs litter the bottom of the water.
This migration, frequent during moulting, exploded this summer.
The spectacular images have even made the rounds on social networks.

This species of crustacean (Maja brachydactyla) usually lives in the English Channel and on the North Atlantic coast, where the water is rather cold.
With the rise in temperatures in the sea, she came to seek the freshness of the Cornish coast, where the water stagnates at 16 degrees.
Tourists do not seem discouraged from swimming, despite the presence of thousands of these long-legged crustaceans.
Because if these sea spiders are venomous for their prey, they remain harmless for humans.
