Ocean currents play a crucial role in shaping the distribution of marine life. They help transport nutrients, plankton, and other food sources which are essential for the survival of various marine organisms. Ocean currents also influence the temperature and salinity of seawater, creating different habitats that support a wide range of species. Additionally, currents can aid in the dispersal of eggs, larvae, and adult organisms, affecting their migration patterns and distribution across different regions of the ocean.
