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.
What are the benefits of an otter?
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.
What would happen if otters were removed from the ecosystem?
At the heart of the food web is a relationship between otters, sea urchins, kelp, and reef-building algae. Without otters, urchin populations flourish and consume the local kelp forests. Rasher discovered that urchins then graze on their next-preferred food: Clathromorphum, the calcifying alga that builds the reef.
How do sea otters protect the environment?
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.
How do otters help with climate change?
In the face of climate change, sea otters can be a powerful ally. In places where they’re thriving, they can maintain and restore kelp forests and coastal wetlands, strengthening our natural defenses against the worst impacts of a changing climate.
How do otters help biodiversity?
As a “keystone species,” they have large-scale effects on coastal marine ecosystems, making them critical to the health of the kelp forests they inhabit. This is because sea otters eat animals, like sea urchins, that graze on kelp and the reefs on which the kelp grows.
Why should we save otters?
Beyond their intrinsic value as a species, sea otters play a critical role in maintaining the kelp forest ecosystem. They are the main predators of kelp-eating species such as sea urchins and abalone. Without sea otters, kelp forests are greatly reduced, resulting in the loss of habitat for many fish species.
Is it cruel to keep otters?
Not only is it cruel and potentially dangerous to keep an otter as a pet, this trend is even putting the very future of some otter species at risk.
What problems do otters cause?
Unlike beavers and muskrats, otters are unlikely to cause structural damage to a pond or stormwater basin. The main issue they pose, however, is fish predation. Otters, like human anglers, like to catch and eat large trophy fish.
How do otters get rid of waste?
But for some animals, pooping is a social event. Instead of “water closets,” North American river otters like to poop in piles near the water, called latrines.
What animals help fight climate change?
‘ The researchers highlighted three key eco-touchpoints where large animals such as elephants, rhinoceroses, giraffes, whales, bison, and moose had the greatest potential to mitigate climate change: carbon stocks, albedo (the ability of surfaces to reflect solar radiation (energy from the sun) and fire regimes.
How do otters reduce carbon dioxide?
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.
What are 3 interesting facts about sea otters?
Sea otter fur is the densest of any mammal at about 1 million hairs per square inch (We have 100,000 hairs on our entire head). Wild sea otters typically have a lifespan between 15 and 20 years. Average weight of an adult female California sea otter is about 50 lbs. Males can weigh up to 70 lbs.
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.
Why do they give otters ice?
It’s not only great entertainment (for them and us!), it keeps them cool and hydrated in the summer heat. It takes a whopping 200kg of ice cubes to keep the otters happy, and during their first year at the aquarium, 24 tons of ice was used to keep them cold.
Why is an otter a keystone species?
The sea otter is considered a textbook example of a keystone species (e.g., Sadava et al. 2016) because of its role as a predator at the top of multiple “trophic cascades” that result in the creation and maintenance of healthy kelp forests and seagrass beds (Estes and Palmisano 1974; Estes et al. 1978; Hughes et al.
Why should sea otters be reintroduced to this ecosystem?
Reintroducing sea otters to areas where they historically lived but are currently absent could help restore functioning coastal ecosystems by enhancing ecosystem resilience, biodiversity, carbon sequestration, and resilience to the effects of climate change.
What species benefit from sea otters?
By controlling the number of crabs, sea otters helped sea slugs and other tiny marine grazers flourish. The grazers in turn kept the eelgrass blades clean and healthy. As sea otters reclaimed their role as predators in this estuary, they helped restore balance to this important habitat connecting land to sea.
What are 5 interesting facts about otters?
30Most otters spend a lot of time on land.
- Sea otters hold hands when they sleep.
- Sea otters sleep together in groups, or “rafts”.
- Otters are part of the weasel family.
- They are adapted to hunt in the water.
- Otters can hold their breaths for a long time.

What otters can teach us?
Play. Otters are some of the most playful creatures in the animal kingdom. When they’re not hunting for food, they love to chase one another, wrestle, and even build water slides. Be like the otter, live with joy and take as many opportunities as you can to play.
Are otters good animals?
Otters are not meant to be kept as pets. These wild animals can suffer stress and anxiety, as well as a range of health conditions, as a result of being kept in a confined enclosure.
