A sandspit is a long, narrow strip of sand that extends out from the shore into the water. This geological feature can be called by many synonyms, such as a barrier spit, a beach spit, or a hook. Other terms for a sandspit include a tombolo, an isthmus, a sandbar, or a shoal. Sandspits are formed by the action of waves and currents, which deposit sediment and gradually build up the landform over time. They are unique habitats that provide shelter and food for birds, fish, and other marine animals. Whether called by its proper name or one of its synonyms, the sandspit is a fascinating and important feature of the coastal environment.
