How do otters affect the ecosystem?
They are predators, meaning they help control the populations of food species they prey upon. This affects the ecosystem as a whole, and as a result, their presence is a signal that the ecosystem is healthy. Otters have thick fur, which makes them attractive to fur hunters.
Why are otters important?
Otters are an essential keystone species. Along the Pacific coast, sea otters help control the sea urchin population. Fewer sea urchins in turn help prevent kelp forests from being overgrazed.
How did the absence of sea otters impact the ecosystem?
The sea otter ecosystem is largely made up of thick kelp forests. Within these forests, sea otters prey on sea urchins, which graze heavily on kelp. If sea otters are not present, then urchin populations boom, which leads to overgrazing — killing all the kelp — and creating a wasteland known as an urchin barren.
How sea otters help save the planet?
In fact, they are now recognised as being a keystone species, whose position in food chains is crucial in maintaining the ecological health of an area. They not only ensure the health of kelp forests but affect many other local species, as Estes's investigations have since revealed.
How do sea otters affect the economy?
The presence of sea otters generates millions of dollars for local economies by increasing ecotourism and helping maintain robust kelp forests (dense groupings similar to forests on land) that sequester carbon and increase fish populations. According to the study, authored by Edward J.
Why sea otters are a keystone species?
Sea otters are a "keystone species" which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
Why did sea otters almost become extinct?
Historically, sea otters numbered in the hundreds of thousands in the North Pacific Ocean, but due to the fur trade, their numbers plummeted in the early 1900s. The threat to the southern sea otter posed by oil spills prompted its listing as a threatened species in 1977.
How can we save sea otters from extinction?
Fertilizers that make their way into the ocean can cause algal blooms, many of which are toxic to sea otters and other marine species. Support legislation and community efforts to improve wetlands. You can also help by supporting legislation protecting sea otter habitats, kelp forests, and marine protected areas.
What is the role of the sea otter in an ecosystem and why are they considered a keystone species?
Sea otters are a "keystone species" which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
Why are sea otters so important to protecting kelp?
The presence of sea otters can protect a kelp forest. They eat large amounts of sea urchins, which keeps the creature's numbers in check and prevents the destruction of the kelp forest. Sea otters are a keystone species of the coastline ecosystem.
What is the value of otter?
How much is Otter worth? The current Otter value is estimated to be around 3,000,000,000 diamonds.
Why are sea otters a keystone species?
Sea otters are a "keystone species" which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
Why are sea otters important to kelp?
Sea otters are a "keystone species" which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
How many sea otters are left 2021?
Sea otter population growth has stalled in recent years and many hurdles for full population recovery remain. There are only about 3,000 southern sea otters left in the wild today.
How do sea otters help to combat climate change?
With the protection sea otters provide, these forests flourish. Kelp forests that are guarded by sea otters can sequester up to 12 times more carbon from the environment. Researchers have found that the presence of sea otters increases kelp forest carbon storage from 4.4 to 8.7 megatons annually.
How does loss of kelp affect sea otters?
The fish and shellfish that depend on the kelp forest will lose their habitat, and their populations will decline greatly. The presence of sea otters can protect a kelp forest. They eat large amounts of sea urchins, which keeps the creature's numbers in check and prevents the destruction of the kelp forest.

Why are sea otters important keystone species?
Sea otters are a "keystone species" which means that they can exert top-down pressure via predation on sea urchins, which are grazers upon kelp. As urchin density decreases from sea otter predation, so does the grazing pressure on kelp and as a result kelp forests flourish in the presence of sea otters.
How do sea otters have an impact on the carbon cycle?
By preying on kelp-grazing sea urchins, otters allow underwater kelp forests to do more of what forests do everywhere: suck up heat-trapping carbon dioxide via photosynthesis.
