Our ecosystem consists of plants and animals that are dependent on each other. The extinction of a single species can negatively affect the entire biological system. The extinction of many marine animals like sea turtles and salmonids have endangered the functioning of the ecosystem and affected the ecological issues. Here are five endangered marine animals that we must try to protect immediately.
It is found in the tropical regions of the world’s oceans, seas, and gulfs. The population of Hawksbill Turtle has reduced by 80% over the last century. It is subjected to heavy trafficking in the tourist trade for its shells and meat. Many countries have stopped harvesting its eggs. The decline in its population is also due to the degradation of the coral reef species on which the Hawksbill Turtle feed on.
Steller Sea Lion
It is the largest member of the Otariid family and the fourth largest seal species in the world. Since the 1960s it’s population has decreased by more than 60%. The reason for this decline is both due to human and natural causes. The harvest by Native Alaskans and Canadians for oil and meat have contributed to the decline in its population. Predation by Killer Whales is also another reason for the lower population.
It can be found in the tropical regions of the oceans. They are being killed for its fin. The process of cutting the fins are very terrifying. The fishermen drag them to board and cut their fins while they are still breathing. Then they are thrown into the water they soon they bleed to death. In many countries, shark finning is banned.
It is the world’s smallest cetacean. Use of gill-netting for fishing is the main reason for the decreasing population of this marine species. The population of Vaquita has been dropping gradually since the 1940s. The population is falling at the rate of 15% per year. It is estimated that 500 to 600 Vaquita will soon become extinct.
It is known the largest living mammal on earth. Commercial hunting has made the population of Blue Whale decline drastically. Even though an international ban order was given in 1966 for catching Blue Whale, this mammal is listed as an endangered marine animal.
Both natural phenomena and human activities are to be blamed for the declining population of these marine animals. We should take action to stop the trade of these animals soon to save them from being extinct.
