deep-sea ecosystems
Deep-sea ecosystems refer to the diverse environments found in the ocean depths, typically below 200 meters (656 feet). These areas are characterized by extreme conditions, such as high pressure, low temperatures, and complete darkness. Yet, they host unique life forms, including bioluminescent creatures, giant squids, and tube worms that thrive near hydrothermal vents. These ecosystems play a crucial role in global processes, such as carbon cycling and biodiversity. Despite their remoteness, deep-sea environments are increasingly threatened by human activities, including deep-sea mining and climate change, highlighting the need for conservation efforts.

Deep-sea ecosystems are found in the ocean's depths, beyond sunlight's reach, at depths of about 200 meters (656 feet) and deeper. These environments host unique creatures adapted to extreme pressures, cold temperatures, and lack of light, such as giant squids, deep-sea fish, and bioluminescent organisms. Nutrients mainly come from the decay of organic material falling from the surface, supporting complex food webs. Deep-sea ecosystems play a crucial role in global carbon cycling and biodiversity, yet they remain largely unexplored and vulnerable to human impacts like deep-sea mining and climate change.
