All can seem calm and tranquil on a sunny day but wild storms stir the sea up. Sometimes these bring with them goose barnacles from their tropical homes on flotsam washed up on the beach.
The Weever fish is an aggressive predator feasting on other small fish and crustaceans. Its tactic is to bury itself under the sand awaiting their prey. This brings them into contact with beach visitors because if trod on, they will inject a poison causing a sting.
Other signs of marine life can be found on the beach amongst the strand line. Look out for mermaids’ purses, really the empty egg cases of rays and skates, related to the sharks.
