Deep Sea Creatures
Deep Sea Creatures are organisms that live below the photic zone of the ocean. They live in very extreme conditions like bars of pressure, small amounts of oxygen, minimal food, no sunlight, and a very cold climate. Deep Sea Creatures depend on food floating down from above. Humans have explored less than 4% of the ocean floor, and new species are discovered with every dive. Extreme differences in the pressure between the sea floor and the surface makes the creature’s survival on the surface almost impossible. As a result, in-depth research is difficult, for the most useful information can be found when the creature is alive.
Animals survive in the deepest parts of the ocean through the physical adaptions of their body. Animals that live within the deepest parts of the ocean are very small, need less to eat, and grow very slowly. Animals that live in this habitat also can withstand very cold temperatures that don’t affect them.
Deep sea creatures see by through their sensitive eyes that can see a range of color hues in almost complete darkness. Deep sea creatures have much more sensitive eyes than human beings do in lower light. Their eyes have light-sensitive proteins that let the retina’s rod cells detect light.
Deep sea animals survive pressure through adaptations in their bodies that include structure, proteins, as well as cell membranes that allow them to withstand the pressure and darkness. Also, creatures that live in the deep sea do not have air sacs in their bodies which prevents them from being crushed by the pressure of the ocean.
