The sea below 200 meters depth accounts for 95% of the volume of the ocean, making it the largest habitat for life on Earth. Though it is perpetually cold, generally dark, and subject to extreme pressures, the deep sea contains a wealth of unique and unusual species, habitats and ecosystems. It also contains a wealth of mineral resources, some of them in unique or highly enriched concentrations.
