What do you think about when you think about the ocean? About the blue waters and waves, about the many creatures and corals? The ocean is a very nice place, isn’t it? But if you looked underneath this disguise, you would find the deep sea. The deep sea, where the pressure is high and the temperature is low. Darkness consumes every inch of this cold, unforgiving biome, and the creatures come on their own nightmare-inducing forms. And the worst part? The deep sea takes up 95% of the whole ocean. Under harsh conditions of their environment, how do deep sea creatures adapt and survive? This article has the answers to that.
Darkness & Vision
In the deep sea, darkness is spread throughout. In other words, the deep sea is pitch dark, and it is hard to see in. The Marine Biology Organization says, “The deepest ocean waters below 1,000 m are as black as night as far as sunlight is concerned”, meaning that starting at 1,000 meters, there is no sunlight for natural lighting in the deep sea. Because of the problem of darkness, deep sea dwellers always have techniques to guide them. Most deep sea creatures cannot see openly, but most of them have a special skill. This “special skill” is called bioluminescence, which is found in their own anatomy! One of the most used examples would be the anglerfish, a special animal of the thousands of fauna from the deep sea. Fauna are a group of animals classified with each other in a group. The anglerfish dangles a light from its forehead, helping it navigate through the blind waters of the deep sea. Not only can bioluminescence be used to see, but it can also be used to lure in curious animals, as seen in the Disney film Finding Nemo.
