Ocean currents play a crucial role in shaping marine life distribution by influencing the movement of nutrients, temperature, and oxygen levels in the ocean. These currents can transport food sources, larvae, and offspring of marine organisms to different regions, affecting their distribution patterns. Additionally, ocean currents can create habitats with specific conditions that are suitable for certain species, leading to the development of diverse ecosystems along their paths. Overall, ocean currents are key drivers of the distribution and diversity of marine life across the globe.
