Test of time
Dense accumulations of tubeworms are common in Upper Greensand pebbles washed onto the beaches around Lyme Regis. Tubeworms secreted a hard, protective shell and then used tentacles to extend out and filter sea water for food. They fed on plankton and any other small items that were washing around. Almost identical tubeworms can be found on the beach today. So, like the much more famous and showy nautilus or the spectacular shark, the humble tubeworm is one of nature’s great survivors, having a lifestyle that has stood the test of time.
