Sea otters are one of the cutest marine mammals to live on our planet. With their bushy fur and big, bright eyes, it’s hard not to fall in love with them.
However, sea otters have been under severe threat due to human activity like many other animals.
If they disappear one day, it could mean serious problems for the aquatic ecosystems of the world and even sea levels. You’ve heard about how harmful pollution is to the environment.
Additionally, you might also be aware that there is a significant amount of fishing going on in the seas, impacting wildlife.
In this article, we will discuss a guide on are sea otters endangered?
Are Sea Otters Endangered?
Yes, sea otters are now classified as endangered as their populations have been steadily declining for many years.
Sea otters are the world’s smallest marine mammal, but they’re also the most fun-loving. They spend much of their time playing in the water swimming or floating on their backs.
Sea otters are weasel family members and have thick fur to keep them warm in cold water.
They have webbed feet that help them swim, and they can close their ears, nose, and eyes while they dive underwater to catch food.
Sea otters are found along the coasts of North America, from Alaska to northern Mexico. The smallest populations live on islands off California.
The sea otter population has been declining because of hunting for their valuable fur and oil, pollution, and loss of habitat due to development.
Sea otters were hunted almost to extinction during the 1700s for their thick fur pelts, used for clothing by Native Americans and Europeans alike.
Sea otter pelts were so valuable that groups of men roamed along the coasts of California and Alaska, killing as many as they could find so as not to waste any time.
Fortunately for these playful creatures, protective laws were passed by Congress in 1911 that banned hunting sea otters throughout all U.S. waters except Alaska (where it is still legal today).
Why Are Sea Otters Endangered?
Sea otters are adorable, cuddly, and just plain fun to watch. That’s why so many people have fallen in love with them and why they’re such popular animals to include in wildlife videos.
Unfortunately, while they are pretty standard and easy to spot, they are also one of the most endangered mammals in the world.
National and international laws protect nearly all otters, but unfortunately, this hasn’t been enough to save these beautiful creatures.
Here are some of the reasons why sea otters are endangered:
Sea Otter Population Is Still Small
The first reason sea otters are endangered is that their numbers are so small. When Europeans first arrived in North America, as many as 300,000 sea otters lived along its coasts.
But by 1911, when Congress made it illegal to hunt or kill sea otters for their fur (which was prized by wealthy Europeans), only about 100 remained along the entire West Coast of North America.
Since then, the population has grown again — but only to around 3,000 today! That’s less than 1% of what it was before European settlers arrived on our shores.
They Were Hunted for Their Fur
The sea otters were hunted for their fur for centuries. The fur was used to make hats, coats, and blankets for people around the world.
They’ve been hunted so much that they almost went extinct in the 1800s! Thankfully, laws were passed to protect these animals from being killed by humans.
Their Habitat Is Being Destroyed
Sea otters live in cold waters along the coasts of North America and Asia.
Unfortunately, their habitats are being destroyed due to pollution from humans and human development on land near the coastlines where they live.
This means that there isn’t enough space left for these animals to live in safety without being disturbed by humans or other problems like pollution and oil spills that can harm them significantly if they come into contact with them while swimming or walking on the shore looking for food or shelter from storms or predators like sharks (which can also kill them).
Oil Spills
Oil spills cause many problems for sea otters because it gets into their fur when grooming themselves with their teeth.
When oil gets into their fur, it prevents them from swimming correctly through the water or staying warm enough in cold waters where they live during winter months in areas such as Alaska and California.
If oil spills aren’t cleaned up quickly enough, they can kill sea otters before they even get sick from them.
Climate Change
Sea otters are vulnerable to climate change because they rely on sea ice for many aspects of their life cycle, including mating and rearing their young.
When sea ice starts to melt earlier in the year or freezes later in the fall, it interrupts the sea otter’s ability to feed on its primary prey, the shellfish that live on it.
This food loss increases competition between otters for food sources and decreases survival rates for newborn pups.
How Many Sea Otters Are Left in the World?
Sea otters are one of the most charismatic marine mammals. They live in the Pacific Ocean and spend most of their time in the water, but they make a lot of noise when they come on land.
Sea otters are significant to their ecosystems because they help keep kelp forests healthy.
The IUCN Red List describes sea otters as vulnerable to extinction because their numbers have declined by more than 50% over the past 100 years.
There are only about 150,000 to 300.000 sea otters left in the world.
They used to be found along the coastlines of Russia, Alaska, Canada, Japan, and China, but now they are only found in Alaska and northern California (USA).
Sea otters were hunted for their fur until they became protected by law in 1911.
However, even though hunting them was no longer allowed, many sea otters died from eating toxic shellfish or getting tangled up in fishing nets.
The Threats Sea Otters Face
The threats to sea otters are many. Although they are protected by law, they are still vulnerable to human activity.
They are hunted for their fur and meat, which is considered a delicacy.
Sea otters must compete with humans for food and habitat because we have put so much pressure on the ecosystem.
The population of sea otters has been reduced by 90% in some areas due to this competition with humans.
The biggest threat to sea otters comes from pollution in the ocean. This pollution affects their health and ability to reproduce.
Pollution is also responsible for the decline of kelp forests that make up their habitat.
As the oceans become more polluted, less oxygen is available for marine life and fewer nutrients for plant life like kelp forests.
Wrapping Up
Sea otters are already considered a vulnerable species, and conservation efforts have been underway for years.
However, scientists predict that the sea otter population could soon become endangered as the numbers decline.
It will be difficult for sea otters to recover if this happens, resulting in areas with fewer of these creatures.
