A large arm of a body of water partly surrounded by land is commonly referred to as a "bay." Bays are typically characterized by their calm waters and can serve as important habitats for marine life, as well as providing sheltered areas for boats and recreational activities. They vary in size and depth, and their shapes can be influenced by geological and climatic factors.
