Animals calling the Abyssal zone home include octopi, fish like the black swallower, tripod and deep-sea angler fish, along with the giant squid, bacteria and several varieties of luminescent crustaceans. The Abyssal zone resides near the bottom of the ocean, having few nutrients, air with high levels of oxygen and very little sunlight. Regardless of these seemingly inhospitable conditions, however, many animals and plants call this zone home, surviving in the cold, dark climate with special features.Continue Reading
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 boast some of the largest eyes in the animal kingdom, with an average diameter exceeding 10 inches. Their large eyes detect large objects, letting the squid navigate through areas with poor visibility. Giant squid feed on other animals, including smaller squid, fish, shrimp and even small whales.Learn more about Zoology
Angler fish are opportunistic foragers, but the most frequent prey of the threadfin angler fish is the pandalid shrimp; however they also eat teleost fish and crustaceans. Scientists determine what angler fish eat by examining their stomach contents. They found over half the fish they examined had an empty stomach, supporting the belief that these fish are low-energy consumers.Full Answer >
Animals with exoskeletons include all arthropods such as insects, crustaceans and spiders as well as many other invertebrate animals such as shelled mollusks. Shelled mollusks include snails, tusk shells, clams, nautilus and chitons. An exoskeleton is essentially an outer skeleton that protects and supports an animal's body.Full Answer >
Mimic octopuses typically eat small crustaceans and fish. They are usually found in muddy river bottoms and estuaries. The species was discovered in 1998, off the coast of Indonesia.Full Answer >
Squids are carnivorous predators that primarily prey on fish, crustaceans and other squid. Because squid vary greatly in size â€“ some species are less than 1 inch in length, while others exceed 30 feet in length â€“ their specific prey preferences differ markedly from one species to the next. Some squid hunt by chasing down their prey, while others hide and lie in wait for food to swim past them.Full Answer >
