As the sea temperature rises, thousands of poisonous crabs pour into St. Ives Beach.
Thousands of poisonous crabs pour into Cornwall Beach, shell themselves and return to the depths of the sea. (Spider crabs— Hyas araneus for Latin — usually congregate in large numbers in shallow water to protect themselves from predators.) ）
Due to rising sea temperatures, the hordes of crabs gathering in the shallow waters of St Ives become more common during the summer months.
While their presence at Porthgwidden Beach is enough to keep many swimmers afraid to go to sea, some do take the opportunity to snorkel over the crustacean colony to see the creepy spectacle.
Once the crabs are out of their shells, they return to a depth of 300 feet, leaving clear water for those who wish to paddle in the water.
Marine photographer Kate Lowe filmed the incident the same week when a female snorkeler was bitten by a blue shark off the coast of Cornwall near Penzance.
Kate said: "I go snorkeling most of the year, but I've never seen so many spider crabs. ”
