"Pelagic" refers to the open ocean environment, away from the coast and the ocean floor. It encompasses the water column and is characterized by its vastness and depth. Pelagic zones are home to a variety of marine life, including fish, whales, and plankton, which thrive in these expansive waters. The term is often used in marine biology to describe organisms that live in the pelagic zone, such as tuna, sharks, and jellyfish. These species are adapted to life in the open sea, where they can travel long distances and find food. Pelagic ecosystems play a crucial role in the overall health of the ocean.
