Why are otters important to the ecosystem?

Why are otters important to 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 otters a keystone species in kelp forests?

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.

How do Southern sea otters act as a keystone species in their environment?

TestNew stuff! Explain how southern sea otters act as a keystone species in their environment. Sea otters prey on the sea urchins, which helps the kelp forests. The sea otters keep the population of sea urchins down, which allows the kelp forests to grow, & helps keeps kelp forests from being destroyed.

Why are sea otters considered to be good indicators of ocean health?

Sea otters, however, have always been a good indicator of marine health. Because they often stay relatively close to the coastline, diseases and parasites that they acquire give scientists a good indication of which pathogens are local and dangerous (Jessup et al. 2004).

Are River Otters keystone species?

Because they have a low tolerance for polluted water, river otters are considered by some naturalists to be a good indicator, or “keystone,” species of the quality of aquatic habitats.

How do river otters benefit the ecosystem?

It’s not a swamp monster—it’s a river otter! 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.

Is a sea urchin a keystone species?

Sea urchins are not a keystone species, although they are an important prey item for many other species.

Where are sea otters a keystone species?

Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem.

How are sea otters indicator species?

Sea otters live in the intertidal zone, making them a key indicator species in determining water quality and aiding researchers discover direct sources of land pollution entering waterways.
