A reference to an organism living on rocky seashores or growing in coastal areas: Sand crabs, sand fleas, clams, and blood worms all are considered to be actophilous creatures that thrive in the sand in coastal regions.

Among many actophilous animals are the barnacles, mussels, snails, and starfish which are a great supply of food for many birds, like terns, gulls, and ringed ployers.
