    There have been thousands of marine species that have become extinct. Currently there are thousands of fish that are endangered and in great need of protection. The following are some.

The Arcadian Redfish are found in warm waters, such as the Atlantic and Indian Ocean. These fish mature at a late age (5 to 6 years) and have low reproductive rates. However, they can live to be 50 years old, which is relatively remarkable. Young redfish are marked with patches of black and green color. They don’t develop their red color until after they move to the ocean bottom. Now the Arcadian Redfish is endangered due to overfishing. These fish started to decrease in population in the early 1900s because of their increased popularity in the food industry.

The Bluefin tuna is one animal that is high on the endangered species list. This fish has been named one of the wonders of the ocean, because they can grow to be 12 feet long and weigh over 1, 500 pounds! Why are these fish disappearing at alarming rates? Because they are being captured for food, with over 75% consumed in Japanese restaurants often by making a popular sushi.

The European Eel is found in the Baltic and the Mediterranean Sea. They have a unique metamorphosis process and they change their forms over a longtime period. According to IUCNRedList.org, the European Eel is one of the threatened species that are not only endangered, but critically endangered.

The whale shark is one of many endangered sharks out there. According to one source, sharks are revered as our last “living” dinosaurs. They are known as the largest fish with the potential to grow over 60 feet long and weigh over 70,000 pounds. The whale shark also has the potential to live to be over 100 years old.
