Abyssals are a type of deep-sea environment found in the ocean's abyssal zone, which lies between 3,000 and 6,000 meters (9,800 to 19,700 feet) below the surface. This region is characterized by high pressure, low temperatures, and complete darkness. Abyssals are home to unique ecosystems that include various organisms adapted to extreme conditions, such as deep-sea fish, crustaceans, and bacteria. The abyssal zone is also significant for its role in the global carbon cycle, as it helps sequester carbon from the atmosphere. The sediment on the ocean floor, known as abyssal plains, is often rich in organic material, providing a habitat for diverse life forms. Research in this area is crucial for understanding marine biodiversity and the impacts of climate change.
