* Sea otters: These small, adorable creatures were almost hunted to extinction in the 18th and 19th centuries for their incredibly dense and valuable fur.
* Harbour seals: While not as targeted as sea otters, their fur was also prized and led to significant population declines.
* Fur seals: Both Northern Fur Seals and Southern Fur Seals were extensively hunted for their pelts, especially during the 19th century.
* Walruses: Their thick, dense fur was used for clothing, and their ivory tusks were also valuable. Walrus populations were significantly reduced due to hunting.
* Polar bears: Though not primarily hunted for fur, their hides were used for clothing and other items.
It's important to remember that all of these species are now protected by international laws and treaties, and the hunting of many of them has been completely banned.
It's also crucial to note that the demand for fur has significantly decreased in many parts of the world, due to both ethical concerns and the availability of synthetic alternatives.
