Deep-sea corals are marine organisms that thrive in the cold, dark depths of the ocean, often at depths greater than 200 meters. Unlike their shallow-water counterparts, these corals do not rely on sunlight for energy. Instead, they obtain nutrients from the surrounding water and from tiny particles that drift down from the surface. Deep-sea corals can form large structures known as coral reefs, which provide habitats for various marine species. These corals are typically slow-growing and can live for hundreds to thousands of years. They play a crucial role in the marine ecosystem by providing shelter and food for diverse marine life, including fish and invertebrates. Additionally, deep-sea corals are important for scientific research, as they can offer insights into climate change and ocean health over long periods.
