The Abyssal zone exists in oceans around the world, and covers the range of ocean extending 6,500 to 20,000 feet below the surface.The variety and population size of life forms diminishes towards the Abyssal zone but, nevertheless, hardy species thrive there, including many fish and invertebrates, such as sea cucumbers and sea urchins.
One of the most impressive inhabitants of this region is the giant squid. These squids reach significant lengths, sometimes covering the length of a school bus in size.

Giant squid feed on other animals, including smaller squid, fish, shrimp and even small whales.Learn more about Zoology
