Main Content

? Tide and Tide Pool Formation: The tide is the rise and fall of the ocean where it meets the land, occurring twice a day. It is caused by the gravitational pull of the sun and moon on Earth. When the tide goes out, small pools of seawater are left behind, forming tide pools, which are mostly found in low - lying areas along rocky shorelines and sometimes on sandy beaches.

? Intertidal Zone and Creatures: The area between high and low tides is the intertidal zone. Different creatures live in different parts of it, such as sea stars, sea urchins, anemones, and jellyfish. Tide pools are full of sea life. The more places there are for animals to hide or attach themselves, the more animals there will be in the tide pool. The substrate in tide pools is usually rocks or sand.

? Survival Challenges: Living in the intertidal zone is difficult for animals. They have to deal with waves crashing over them and the threat of being exposed to air and the sun. In addition, human activities such as trampling and collecting organisms also affect the ecosystem of tide pools.
