What kinds of conditions do organisms need to be adapted for in the intertidal zone of the ocean?

Organisms in the intertidal zone need to be adapted to survive rapid changes in temperature, salinity, and oxygen levels as the tide rises and falls. They must also be able to withstand the physical stress of waves, strong currents, and exposure to air during low tide. Additionally, they need ways to avoid desiccation and cope with competition and predation in a dynamic and crowded environment.
