A piece of shallow saltwater separated from the deeper sea by coral or sand is called a lagoon. Lagoons are commonly found in coastal areas and are formed by the accumulation of sediment, such as coral reefs or sandbars, which create a barrier between the open sea and the shallow water.

The water in a lagoon is typically calm and clear, making it an ideal habitat for various marine species, including fish, mollusks, and crustaceans. The unique ecosystem of a lagoon provides a safe haven for these organisms, as the barrier created by the coral or sand offers protection from strong waves and predators.

One of the most famous examples of a lagoon is the Great Barrier Reef in Australia. This natural wonder is composed of thousands of individual reefs and lagoons stretching over 2,300 kilometers. The coral formations within the lagoon support an incredible diversity of marine life, making it a popular destination for snorkeling and diving enthusiasts.

Lagoons also play a crucial role in coastal ecosystems by acting as a buffer zone between the land and the open sea. The shallow water and vegetation found in lagoons help to filter pollutants and prevent erosion, ultimately contributing to the overall health of the surrounding environment.

In addition to their ecological importance, lagoons have significant economic value. Many coastal communities rely on lagoons for tourism, as they attract visitors who are interested in experiencing the unique beauty and biodiversity of these environments. Lagoon-based activities such as boating, fishing, and bird watching contribute to the local economy and provide employment opportunities.

In conclusion, a lagoon is a shallow saltwater body separated from the deeper sea by coral or sand. These unique ecosystems support a diverse range of marine life and play a vital role in coastal ecosystems. Whether it be for ecological or economic reasons, lagoons are cherished and appreciated by both nature enthusiasts and local communities.
