What ecosystem do otters live in?
They can thrive in any water habitat, such as ponds, marshes, lakes, rivers, and estuaries—in cold, warm, or even high-elevation areas—as long as the habitat provides adequate food. River otter dens are along the water in abandoned burrows or empty hollows.
What is the habitat of a Eurasian otter?
The Eurasian otter lives in a wide variety of aquatic habitats, including highland and lowland lakes, rivers, streams, marshes, swamp forests and coastal areas independent of their size, origin or latitude (Mason and Macdonald, 1986).
Are otters good for the ecosystem?
As top predators, sea otters are critical to maintaining the balance of nearshore ecosystems, such as kelp forests, embayments and estuaries. Without sea otters, sea urchins can overpopulate the sea floor and devour the kelp forests that provide cover and food for many other marine animals.
Why are river otters important to the ecosystem?
Otters also have a pivotal role in river ecosystems. 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.
Do sea otters live in kelp forests?
One of the most important mammals in a kelp forest is the sea otter, who takes refuge from sharks and storms in these forests. The sea otter eats the red sea urchin that can destroy a kelp forest if left to multiply freely.
Where do most sea otters live?
Range. Southern sea otters can be found along California’s central coast, from San Mateo County in the north to near Santa Barbara in the south. Northern sea otters are found along the coast of Alaska and Washington, and Russian otters are found in the Pacific Ocean off Russia and Japan.
Why are European otters endangered?
The Eurasian otter (Lutra lutra) is an endangered species that is threatened by loss of habitat as well as water pollution. In many regions across Europe the otter also comes into conflict with fish farming, which shares the same ponds and streams.

How do otters help prevent climate change?
Sea otters help ecosystems capture carbon from the atmosphere and store it as biomass and deep-sea detritus, preventing it from being converted back to carbon dioxide and contributing to climate change.
What are otters good for?
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 otters keep the kelp forest ecosystem stable?
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.
Why are Eurasian otters important?
Otters are top predators using both terrestrial and aquatic environments and their loss has a serious impact on local food webs, biodiversity and habitat relationships. Otters live in many different aquatic environments – coastal, estuaries, rivers, lakes, canals, marshes, etc.
