Shore boulder. View of a barnacle- and whelk- covered boulder on a rocky shore at low tide. Barnacles (grey crust) are small crustaceans which filter their food from the water when covered by the tide. They close up their shells when the tide goes out to avoid drying out. Dog whelks,Nucella lapillus,are predatory gastropods (pale,spiralling shells). They feed on the barnacles along with other small animals and carrion | |
