These forms live chiefly on the naked rock, but, except the limpets, also often on the algae in the tidal area. But when the belt of fucoids is exposed at ebb- tide, especially in sheltered places where a good current runs, we see that the algae, the species of Fucus in particular, have their special Fig. 319. fauna, consisting chiefly of attached forms.
