The sublittoral zone is home to anemones, crabs, sea stars and coral. The sublittoral zone is another name for the deepest region of the intertidal zone.Know More
The littoral zone is the region of ocean extending 600 feet out from the shore. Three sub-zones comprise the littoral zone: the supralittoral, eulittoral and sublittoral zones. The sublittoral zone extends to a depth of about 650 feet and is continuously below water. Coral and anemones are more plentiful in the sublittoral zone than in other regions of the intertidal zone because the zone is comparatively more stable in temperature and the amount of sunlight it receives. Sea stars and sea urchins also take advantage of the warm, sunlit waters of the sublittoral zone.
On North America's west coast, the dungeness crab is an economically important intertidal resident. These crabs reside in beds of eelgrass on the sublittoral ocean floor, scavenging ocean carrion and preying upon small fish and other crustaceans. While the dungeness crab is an important food crustacean on the west coast, concerns have arisen about its introduction in the Atlantic and its possible effects on native fauna.
Algae and plantlife are also plentiful in sunny sublittoral waters. This provides an excellent food source for much of the intertidal fauna. However, excessive algae and plant material can block sun from the ocean floor and cause overcrowding for other species.Learn more about Marine Life
Sea anemones have the potential to live from 60 to 80 years or more. As they do not age, the Cnidarians are able to live indefinitely, though they often fall victim to predators long before they reach their expected lifespan.Full Answer >
The twilight zone, also called the mesopelagic zone, is home to many species of squid and octopus, as well as some bioluminescent fish, including the hatchet fish. Some jellyfish-like animals called ctenophores and siphonophores live in the zone as well.Full Answer >
The abyssal zone is home to a number of animals such as the deep-sea anglerfish, the black swallower and the giant squid. Generally, larger creatures that are able to withstand the pressure of the ocean's depths live in the abyssal zone.Full Answer >
Animals that live in the ocean include marine mammals such as dolphins and whales and many kinds of marine fish. Crustaceans such as lobsters, crabs and shrimp also live in the ocean, as do mollusks such as squid and octopuses.Full Answer >
