For an article from an online journal.
Woods Hole Oceanographic Institution. “Solving an evolutionary puzzle: Atlantic killifish thriving in highly polluted water.” ScienceDaily. Science Daily, 12 February 2014. www.sciencedaily.com/releases/2014/02/140212144607.htm.
In this article it talks about a certain type of fish that can not only tolerate polluted water but actually thrives in it. The type of fish is called an Atlantic killifish, they are only about three inches long, and unlike normal fish they stay in one place for their whole lives. Researchers found these fish in the New Bedford Harbor. At the beginning of the article it asks the question, “How have they been able to adapt and live in such a highly contaminated environment?” The authors states that researchers have found a factor that gives the killifish a resistance to the polluted water, there was a change in receptor protein, aryl hydrocarbon receptor 2 or AHR2. An important fact of the killifish is even though they can tolerate the polluted water the contaminates are still affected whatever eats them such as bluefish, striped bass, and more that are also eaten by humans. Therefore, even though these fish have a special treat it can affect other fish and humans.
I chose to do the article because ever since I was little I have been interested in fish. At my old house we have a big aquarium filled with different corals and fish. Every time we got a new fish I would always watched to see where it would go and all sorts of things. So finding an article about these very different and cool fish just sparked my interest right away. One fact about the killifish that relates to a certain fish I had was that they do not migrate. I had a clown fish and it would always be in the same coral.
I enjoyed reading this article because it had a lot of information. A good part of the article is it asked the question, “How have they been able to adapt and live in such a highly contaminated environment?” I liked that the author asked this question because it asked the question that everyone is thinking and the author does a good job answering it. While reading the article I felt that they used too many abbreviations and I could not remember what meant what. Overall it was an interesting article.
