Organisms that inhabit intertidal zones must be able to tolerate radical changes in temperature, salinity, and moisture and also be able to withstand wave shock. Intertidal zone is the coastal area alternately exposed and submerged by tides. Tide pool animals and plants are well adapted to the intertidal zones. Some adaptations include; the ochre sea star can tolerate a longer time period exposed to air than many other sea stars. They regularly withstand up to eight hours of exposure during low tides.
