The world's oceans, comprising over 70% of the Earth's surface, harbor an extraordinary diversity and abundance of marine life. This vibrant ecosystem sustains an array of organisms, from microscopic plankton to colossal whales, thanks to factors such as temperature variations, sunlight availability, and the presence of critical nutrients. The oceans' vast size provides ample space for species to thrive in different habitats, and its interconnected nature allows for the exchange of nutrients and organisms. Furthermore, the unique chemistry of seawater, containing essential elements like sodium, chlorine, and oxygen, supports the physiological needs of marine life. These factors collectively create a complex and interconnected system that sustains the astonishing biodiversity and productivity of the world's oceans.
