Blue Planet - Tidal Seas
The periodic movement of ocean water along the coasts, from low tide to high tide, creates an ecosystem that is exposed to both land and water. This confluence results in a unique biodiversity, with both plant and animal organisms adapted for gathering food from the incoming high tide, while being able to survive the dryness of low tide.
