This species extends in the intertidal zone, with its largest populations in the middle and upper-middle horizons, together with communities of cyanobacteria and populations of sacbocaos (Chthamalus stellatus). Due to the semidiurnal tidal regime, this species goes through periods of prolonged emersion, and in times of strong insolation suffer great water stress that can be irreversible. (Núñez et al., 2003)
