What types of adaptations might marine animals need to have near the surface versus near the bottom? Ocean animals with cool adaptations. Marine animals breathe air or extract oxygen from the water. They range in size from microorganisms that can only be seen with microscopes and provide the base for many food chains to the mammoth blue whale that can be up to 110 feet long. Answer: There are several ways deep-ocean animals survive in such an environment. The sperm whale is thought to be able to dive more than 1 1/2 miles below the ocean surface.

Now that you're living in the ocean, you'll have to enjoy eating seafood! Adaptations that have helped solve this problem include the reduction of surface area and the increase in internal volume, a fatty layer of blubber under very thick skin, and a reduction in the amount of blood going to areas in contact with the cold water. They create energy from sunlight, feed countless animals, and can grow and thrive under almost any conditions on earth. 4. Marine mammals are still warm-blooded and have to keep the temperature of their bodies above that of the ocean. {{courseNav.course.topics.length}} chapters | This octopus-like creature can change its color and shape to hide from predators.

The open ocean, or pelagic zone, consists of everything in the ocean outside of coastal areas. It is known that animal life can be found at all depths of the ocean, from the surface to the deepest trenches that are over seven miles below the surface. By Avery Hurt. The pelagic zone can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom. Fish can drink salt water, and eliminate the salt through their gills. Chelonia mydas Young turtles living in the open-ocean feed on small invertebrate animals. Plant adaptations are not more rudimentary than animal adaptations. Open Ocean : The vast open ocean and deep sea are home to delicate jellyfish, light-producing animals, and other organisms ranging from the beautiful to the bizarre.
