The Impact of Sea Otters on Marine Ecology

Enhydra lutris is a marine mammal that can live a whole life in the water. They are carnivorous and eat sea urchins, crabs, fish, mussels, and clams. They are called main species because they have a major impact on the marine ecosystem. The interaction between sea otters, sea urchins and algal forests was studied as a model of predator-prey interaction in community ecosystems. Sea otters are important predators and their presence has a major impact on the ocean's food net, especially by affecting the sea urchin population, as well as algae forests and other marine organisms.

Sea otter is the smallest marine mammal, the largest member of the weasel family. Sea otters have three variants. It is southern sea otter, northern part, Russian. This report explains why three subspecies and sea otters were depleted in the past and why they are kept in danger today. & Lt; Tab / & gt; In 1741, a Russian explorer discovered a sea otter on the coast of Russia and Japan. They soon realized that their fur thickness and temperature were twice that of fur seals. It soon became very valuable in places like Europe and China where it was called "warm gold". Russians quickly enslaved Alaska's natives as aleucians to help massacres. When hunting the peak in San Francisco Bay, California, 500 to 600 otters are killed each week. Before all this happened, there were around 150,000 to 300,000 sea otters in the world.

One of sea otters' main food sources is sea urchins. Ecological release of the sea urchin population occurs when the hunter decreases the sea otter population. After that, sea urchin exploited seaweed which is their main food source, made sea urchin barren, seaweed was deprived of seaweed, but sea urchin was on the carpet. Sea urchin no longer eats food, and it is extinct in this area. In addition, because the kelp forest ecosystem is the habitat of many other species, loss of algae causes other cascade effects of secondary extinction.

Sea otters suppress the number of sea urchins and sea urchins suppress the growth of kelp. In the absence of sea otter, sea urchin eats all the seaweed and creates barren lands without seaweed. When the sea otters were reintroduced, the number of sea urchins decreased and a rich seaweed forest came back. Sea otter predators trigger an increase in kelp through double regulation. Are not you thinking that you are no longer creative and uncontrolled, or anything else you want? In that case, the expected quality may be hindered by others. If you want a higher quality than you need, you will not ignore the driving force that hinders you. You have to stop what is stopping you
