Although the deep sea has been thought of as inhospitable and barren, it is populated by a huge diversity of organisms and is one of the most exotic ecosystems on earth without any light, consistent clod, and incredible pressure. Most species lack color or are completely black; have adapted very particular feeding habits; are able to produce light through bioluminescence; and have striking reproductive procedures. These organisms can be gigantic and live for centuries, and rely on chemosynthesis as opposed to photosynthesis for the energy of life. Examples are given of some of the deep ocean species. The potential of the deep sea for bioprospecting and the need to protect this habitat have been recognized. This video is licensed under the CC BY-NC-SA license.
