What characterizes the pelagic zone of the ocean?

The pelagic zone of the ocean is characterized by its vast open waters that exist beyond the coastal regions and the continental shelf. Within this zone, a diverse array of mid-water organisms thrive, including various species of fish, marine mammals, and plankton. This region is significant as it is home to the majority of the ocean's biomass and supports complex food webs that include both phytoplankton and larger predators. The dynamic environment of the pelagic zone is influenced by factors such as light penetration, water temperature, and the availability of nutrients, which contribute to its rich biodiversity.

Understanding the specific characteristics of the pelagic zone is essential for comprehending marine ecosystems and the ecological interactions within them. This diversity is what makes the pelagic zone stand out in contrast to other areas of the ocean, such as the deep sea trenches or coastal regions where different types of fishing and species composition are observed.
