deep sea fish-Yurika

              This week, we have read the article about the deep sea. According to, “Is Deep-Sea Exploration worth the Money?”, the writer asserts that deep sea exploration can help our lives and have a lot of value for us. After that, I thought how about deep sea fishes because the writer doesn’t mention about deep sea fish. Have you heard of deep sea fish? Do you know how they live in the deep sea? As the writer says, we found the chemicals which can help developing medicines from deep sea fishes. Deep fishes contain a lot of helpful chemicals. Knowing about deep sea fish can help us to more understand the earth, which we live in.

              First, what is the deep sea fish? Generally, we call fishes which live in below 200 M Ocean as deep sea fish. Also, they live in the sea which is darkness and silent. And they usually eat marine snow, made from dead fishes and plankton. They have unique styles because they have to live in a harsh environment which doesn’t have plenty of food and enough warmth. We have found two thousand kinds of deep sea fish, and they can identify two types of deep-sea fish. One of them is deep sea fish live in the bottom of ocean. The anther one is deep sea fish live in the sea below 200m to 800m.

              Second, some of deep-sea fishes have body parts which can emission. Generally, they have it because of predation. An example of this is Atlantic Football fish, known as the man-gobbler. They light up their faint feed. On the other hands, some of them have this because of communication. They emit light to communicate with a member of parties. In addition, they use this parts of body to escape from enemies. It can make easy situations to escape because it can be a dummy for enemies.

              Third, why are there no fish in the deepest deep sea? Here is a mystery that below 8,400 meters there are no fish. We have discovered some tiny worms, but no one has seen a fish. We simply assume that because of pressure. We must have experience that when we tried to dive to the bottom of a pool, we felt a squeeze in our ears. It can make difficult to live for fish. Even for us, it is the biggest problem to go to deepest deep sea. Now we only can go to below 8,000m. 

              Now, I getting feel importances of deep sea fish as well. It’s not just a sea which darkness, it is a light to develop our lives!!
