The barrier reefs.

A barrier reef is a type of coral reef that is found along the edges of continents and islands. It is separated from the shore by a deeper channel or lagoon and is usually larger and more stable than a fringing reef.

Barrier reefs are found in tropical and subtropical waters around the world, including the Great Barrier Reef off the coast of Australia, the Belize Barrier Reef in Central America, and the Andros Barrier Reef in the Bahamas.

Barrier reefs are formed when coral grows on top of an older, submerged reef or on the edge of a continental shelf. Over time, the coral builds up, creating a wall or barrier that extends from the shore out into the deeper waters of the ocean. The lagoon that is formed between the reef and the shore is usually shallow and protected, making it a popular spot for swimming, snorkeling, and diving.

Barrier reefs support a diverse community of plants and animals, including coral, fish, invertebrates, and other marine life. They also provide a range of ecological and economic benefits, such as protecting coastlines from erosion, supporting local economies through tourism and fishing, and playing a role in global climate regulation. However, like all coral reefs, barrier reefs are facing many challenges, including climate change, pollution, and overfishing, which threaten their survival and the ecosystems they support.
