دریائی refers to anything related to the sea or ocean. This term is often used in various contexts, including marine life, oceanography, and maritime activities. The sea is home to a diverse range of organisms, from tiny plankton to large whales, and plays a crucial role in Earth's ecosystem. In addition to its biological significance, دریائی also encompasses human activities such as fishing, shipping, and tourism. Coastal regions often rely on دریائی resources for their economies, while researchers study ocean currents and climate patterns to understand their impact on the environment.
