History of Sea Otter Awareness Week
Sea Otter Awareness Week celebrates a small and underrated creature. Otters have been around centuries before us. They date back to the Miocene age, roughly five to 23 million years ago. If you look beyond their cuteness, you’ll see an animal essential for our survival. Otters are keystone species that have a significant role to serve. They create a balance in the ecosystem by controlling the sea urchin population. This is especially essential as sea urchins overfeed on kelp and have destroyed much coastal kelp. Maintaining kelp forests reduces the effects of climate change, reducing carbon dioxide.
The International Fur Seal Treaty of 1911 saved sea otters from extinction by banning the hunting of sea otters and other keystone species, though their population continues to fluctuate throughout the years. In 1977, sea otters were littered in the Endangered Species Act, but conservation groups, such as the Defenders of Wildlife (founded 1947), played a great role in the recovery process. In 2006, Defenders of Wildlife aided in establishing the California Sea Otter Fund, allowing taxpayers to donate to the cause.
Sea otters have since recovered due to the advocacy of wildlife conservation groups and government intervention, but the effects of overhunting sea otters are still felt. Sea otters continue to face challenges. Their main threats are man-made: oil spills, fishing gear entailment, vessel strikes, and habitat degradation due to pollution and global warming.

Sea Otter Awareness Week FAQs
When is Sea Otter Awareness Week?
Sea Otter Awareness Week 2026 runs from Sunday, September 20, through Saturday, September 26, inviting everyone to learn about these vital marine mammals.
How many sea otters are left in the wild?
While populations vary by region, the southern sea otter population in California was estimated at around 3,000 individuals in the most recent surveys. Global numbers are significantly higher but still a fraction of historical levels.
Why are sea otters considered a keystone species?
Sea otters are a keystone species because their presence significantly impacts the entire ecosystem. They primarily feed on sea urchins, which, if left unchecked, can decimate kelp forests.
What are the biggest threats to sea otters?
Sea otters face numerous threats, including oil spills, habitat degradation, entanglement in fishing gear, and predation. Their dense fur, while insulating, makes them highly vulnerable to oil contamination.

Sea otters will and do cover themselves in kelp or seaweed to keep from floating away from each other and to protect themselves against predators.
