This video takes us deep underwater to observe deep sea creatures. The term deep sea creature refers to organisms that live below the photic zone of the ocean. These creatures must survive in extremely harsh conditions. The water is between 3 and 10 degrees Celsius (37.4 and 50 degress Fahrenheit) and has low oxygen levels. Due to the depth, the pressure is extremely high, between 290 and 14,503 psi. Deep sea creatures also often have to wait for food to float down from above. Creatures that live hundreds or even thousands of meters deep in the ocean have adapted to the high pressure, lack of light, and other factors.
