The word "Syrt" refers to a sandbank or shallow water area off the coast. It is also known by other names such as shoal, sandbar, sandspit, and tidal flat. These synonyms describe similar features of the seafloor and are often formed by natural processes such as erosion and sedimentation. Shoals and sandbars can be dangerous to ships, as they can cause the vessels to run aground or capsize. Tidal flats are important habitats for a variety of marine life, including birds, fish, and shellfish. These different terms are used interchangeably to describe the various features that occur underwater and close to the shoreline.
