The deep-sea ecosystem is a unique environment found at depths of over 1,000 meters in the ocean. It is characterized by extreme conditions, including high pressure, low temperatures, and complete darkness. Despite these challenges, a variety of organisms thrive here, such as deep-sea fish, crustaceans, and bioluminescent organisms, which have adapted to survive in this harsh habitat. These ecosystems play a crucial role in the Earth's overall health. They contribute to the global carbon cycle by sequestering carbon and supporting diverse food webs. Additionally, deep-sea habitats, like hydrothermal vents and cold seeps, provide unique resources and potential for scientific research, including the discovery of new species and biotechnological applications.
