The deep has always bee a food limited habitat. Energy in the form of organic matter has sunk and provided much needed resources to the deep sea providing a wealth of biodiversity. Whales the largest mammals, are large enough to sink whole when they die and provided a huge energy input due to their size. The whale carcass acts as an island for diversity allowing for mega-fauna, macro-fauna and micro-fauna to flourish. The habitats even act as stepping stones between hydrothermal and cold seep sites. This unique chemoautrotrophic system is affected by human activites, mainly whaling, as a result of decreasing the amount of whale falls to the deep.
