The biome located between the highest and lowest tide is called the intertidal zone.

Here's a little more about it:

* Location: This zone is the area along a coastline that is submerged during high tide and exposed during low tide.

* Conditions: The intertidal zone experiences extreme fluctuations in temperature, salinity, and exposure to air and water. Organisms that live here must be adapted to these harsh conditions.

* Diversity: This zone is home to a variety of plants and animals, including seaweed, barnacles, mussels, sea stars, crabs, and shorebirds.
