Deep sea communities

Deep sea communities are groups of organisms associated by a shared habitat in the deep sea. They remain largely unexplored, due to the technological and logistical challenges and expense involved in visiting these remote biomes. Because of the unique challenges (particularly the high barometric pressure, extremes of temperature and absence of light), it was long believed that little life existed in this hostile environment. Since the 19th century however, research has demonstrated that significant biodiversity exists in the deep sea.
