The term "bathypelagic" refers to a layer of the ocean that lies between 1,000 and 4,000 meters (3,280 to 13,123 feet) below the surface. This zone is characterized by darkness, high pressure, and cold temperatures. It is home to unique marine life adapted to these extreme conditions, including species like the giant squid and various bioluminescent organisms. Bathypelagic waters receive very little sunlight, making photosynthesis impossible. As a result, the food web in this zone relies on organic matter that sinks from the upper layers of the ocean. This layer plays a crucial role in the global carbon cycle, helping to sequester carbon deep in the ocean.
