Toitevahemikud, also known as intertidal zones, are the areas of the shore between the high and low tide marks. These zones are characterized by a dynamic environment where the water level fluctuates with the tides, creating a unique ecosystem that supports a diverse range of plant and animal life. The intertidal zone is influenced by both marine and terrestrial factors, making it a critical habitat for many species.

The intertidal zone can be further divided into several subzones based on the frequency of submersion. The supralittoral zone is the area above the high tide mark, where organisms must tolerate prolonged exposure to air and sunlight. The eulittoral zone is the area between the high and low tide marks, where organisms experience regular submersion and exposure. The sublittoral zone is the area below the low tide mark, where organisms are submerged for most of the time.

The intertidal zone is home to a wide variety of organisms, including algae, barnacles, mussels, sea stars, and various types of birds. These organisms have adapted to the challenging conditions of the intertidal zone, with some species using air bladders or other mechanisms to stay afloat during low tide. The intertidal zone also plays a crucial role in nutrient cycling and carbon sequestration, contributing to the overall health of coastal ecosystems.

Despite their ecological importance, intertidal zones are often threatened by human activities such as coastal development, pollution, and climate change. Efforts to protect and conserve these valuable habitats are essential for maintaining the biodiversity and resilience of coastal ecosystems.
