EVERYDAY SCIENCE

Detailed explanation-1: -Anything living in the intertidal zone must be able to survive changes in moisture, temperature, and salinity and withstand strong waves. Intertidal zones of rocky shorelines host sea stars, snails, seaweed, algae, and crabs.

Detailed explanation-2: -2.2. The intertidal zone can experience extreme temperature changes within a single day. The organisms in this zone must be resistant to these changes to survive. Most of the marine organisms are ectothermic and need the warmth from the environment to survive.

Detailed explanation-3: -Many animals avoid sun, drying air and predators such as birds, by staying in cracks, under rocks or in their own burrows at low tide. Some sessile animals such as barnacles and oysters close their valves tightly to avoid drying when the tide goes out. They come out to feed when covered by water.

Detailed explanation-4: -This is also the zone that is most affected by wave action, which can cause wave shock. Many animals in this zone have shells or hide under rocks to avoid waves. The algae and animals in this zone must be securely attached to the substrate.

Detailed explanation-5: -The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.
