What are the different types of endangered sea animals?

There are many different types of sea animals for many different reasons on the list of endangered species. Often human influence, such as ships, fishing, coast and pollution, attribute a high number of deaths in these sea animals. The causes of reduction of the number are sometimes unknown. Sea mammals, such as whales, manatees and dugongs, have decreased significantly in the number, along with turtles, some sea birds, sharks and salmon. Human risk is not only represented from fishing, hunting and whales, but also from boat accidents. This is particularly common in shallow swimming animals that breathe air, such as various types of sea mammals and turtles. Pollution can also add to the list of endangered sea animals.

Many types of sea turtles are at risk. This phenomenon often follows from the dangers of animals. The turtle eggs are laid on the ground that will be played destroyed by urban development near the shores. Coast -centers and tourist areas tend to pose a threat to many types of seaof the animals. In particular, the true whales and whales have seen a dramatic reduction in the number and faced critical threats. The number of whales in the northern Atlantic decreased dramatically for unknown reasons, but it is assumed that it did not cause the whaling independently. This can be the result of ships, pollution or reproductive problems between animals.

Reasons for reducing the number of manate and dugongs are assumed that they come from a high number of fatal collisions of ships. Due to the gray color of these animals, people in ships have difficulty to see. In addition, Manatees and Dugongs are very slowly in motion and may have difficulty leakage of a fast -moving ship. A high number of prenatal deaths have been reported by such animals for reasons that biologists unknown.

different types of seabirds were threatened, including a brown pelican. This bird, which once commonly found between northern, medium and southern andMerik, faced a large number of deaths due to egg crushing during incubation. It is believed that the egg shells of these birds were dangerously thin due to the use of dichlorodiphenyltrichloethane (DDT). Since the end of the 20th century, many forms of DDT have been banned in the United States.

penguins also got on the list of endangered sea animals. As a result of excessive fishing, food supplies for the Humboldt penguin, which is found in Chile and Peru, have reduced significantly. Many deaths between these penguins were also attributed to fisheries.

Salmon, although often considered fish with fresh water, are also considered part of the list of endangered sea animals. These fish emerge in Fresh water, but swim where the rivers and streams meet the sea. A decrease in water quality due to pollution reduced the number of salmon. Water driving water, such as dams, also adversely affected salmon friction.
