Tidal Zones:
* High Tide Zone (Supratidal): This area is only submerged during the highest tides. It's mostly exposed to air and often experiences extreme temperatures and salinity fluctuations.
* Organisms: You'll find hardy organisms like:
* Seaweeds: (like rockweeds) that can tolerate desiccation (drying out).
* Barnacles: that can close tightly to retain moisture.
* Periwinkles: small snails that can survive out of water for extended periods.
* Mid Tide Zone (Intertidal): This is the zone that is regularly exposed and submerged with the tides. It experiences a wide range of conditions.
* Organisms: The diverse mid tide zone is home to:
* Eelgrass: (actually a flowering plant) is an important primary producer, providing food and shelter for many organisms.
* Algae: Various species of algae thrive in the intertidal, contributing to the food web.
* Fish: Some species, like tidepool sculpins, can survive in tidal pools.
* Shrimps: Especially young shrimp, may inhabit the intertidal zone.
* Crabs: A variety of crabs, such as shore crabs and fiddler crabs, live in this zone.
* Sea stars: These predatory invertebrates are common in the mid tide zone.
* Sea anemones: Attached to rocks, these animals have stinging tentacles to capture prey.
* Low Tide Zone (Subtidal): This zone is constantly submerged and is home to a rich diversity of life.
* Organisms:
* Dolphins: While not specifically tidal zone inhabitants, dolphins may venture into shallow, coastal waters that are part of the subtidal zone.
* Fish: A huge variety of fish species live in the subtidal zone.
* Sea urchins: These spiny invertebrates graze on algae.
* Sea otters: These playful marine mammals can be found in the subtidal zone in some regions.
* Larger marine life: As you move further down into the subtidal zone, you'll find larger animals like sharks, whales, and other marine mammals.
Important Notes:
* Habitat Variation: The specific organisms found in each zone will vary depending on location, latitude, and other factors.
* Species Adaptation: Organisms living in tidal zones have developed special adaptations to cope with the changing conditions.
* Interdependence: The various organisms in the tidal zones are interconnected, forming complex ecosystems.
