Marine Biology

Marine biology is the scientific study of life in the ocean and other saltwater environments, examining the vast diversity of organisms from microscopic plankton to the largest whales. As a specialized field of biology, it investigates the physiology, behavior, and distribution of marine life, while its strong ties to ecology and conservation focus on how these organisms interact with their environment and each other within complex ecosystems like coral reefs and the deep sea. A critical component of this discipline involves understanding and mitigating the impacts of human activities, such as pollution, overfishing, and climate change, to preserve the health and biodiversity of the world's oceans.
