Why do sea otters keep stealing surfboards in Santa Cruz? Earlier this month, a sea otter swam straight at a youth surf club at Steamer Lane and climbed onto a surfer's board until one of the kids charged it away. It's the latest in a run of encounters at the same famous break, from Otter 841's viral summer of 2023 to a surfer who was nipped on the foot and lost her board to an otter for about 20 minutes in October 2025. Marine biologist Andrew Lewin, host of Ocean Decoded, looks underneath the viral clips to ask why otters at this one spot keep losing their fear of people, and what that costs the otters.
Otter 841 was born in captivity to a mother, Otter 723, who had been pulled from the wild after people fed her and she started approaching kayakers. 841 was released in 2020, tried to take boards from surfers in 2023, avoided every capture attempt and had a pup that October. Her tracking tag is gone, so nobody can say whether this month's otter is her, one of her offspring or another otter that learned the same habit. That matters for the species. The fur trade nearly wiped sea otters out, and every southern sea otter alive today descends from about 50 survivors found off Big Sur in 1938. Around 3,000 live in California now, listed as threatened and covering about 13 percent of their historical range. As a keystone species, they eat the sea urchins that would otherwise strip kelp forests bare.
The U.S. Fish and Wildlife Service has linked aggression in female southern sea otters to hormonal surges or to being fed by people. Constant disturbance on crowded shorelines and growing up around humans may add to it. Otters have no blubber and burn huge amounts of energy to stay warm, so every disturbance costs them calories, and an otter that becomes a public safety problem can lose its place in the wild for good. Under the Marine Mammal Protection Act, approaching an otter closely enough to change its behaviour can count as harassment. You can help: give otters room (USFWS advises kayakers to stay at least 60 feet from resting otters), never feed them, report anyone who does, paddle calmly away if one approaches, and share viewing guidance along with the clip. Watch Ocean Decoded Live, Monday to Thursday at 5 PM Eastern, and listen to How to Protect the Ocean and Beyond Jaws, which Andrew co-hosts with Dr. David Ebert.

Takeaways:
A sea otter climbed onto a youth surfer's board at Steamer Lane this month, the latest in a string of encounters at the same break.
Otter 841 made the behaviour famous in 2023. Her tag is gone, so this month's otter can't be identified.
841's mother was removed from the wild after people fed her and she began approaching kayakers.
If several otters share the behaviour, the cause points to the place and to people more than to one animal.
Every southern sea otter today descends from about 50 survivors found off Big Sur in 1938, and the population is around 3,000.
Sea otters are a keystone species that keep urchins in check so kelp forests can grow.
USFWS links aggression in female otters to hormonal surges or human feeding. Constant disturbance may also play a part.
Disturbance costs otters energy they have to replace by diving and hunting.
Approaching an otter closely enough to change its behaviour can count as harassment under the MMPA.
Give otters room, never feed them, report feeding, paddle away calmly and share viewing guidance with every clip.
