As COVID-19 travel restrictions begin to ease after more than a year, many people are heading to California’s Central Coast. Morro Bay’s beautiful scenery and wildlife continue to draw visitors and locals to its shores. While we’re there, watching the waves wash over the sand and the sea otters play, we can do our part to help keep this incredible place as gorgeous, healthy, and wild as it is today for years to come.
In this post, you’ll learn how to get a great view of Morro Bay’s sea otters without disturbing them. This gives you a better chance of seeing them groom, rest, hunt, eat, and care for their pups, as they normally would. And, it gives them a better chance of surviving and thriving in the cold waters of the bay.
When humans and sea otters overlap
Whenever sea otters and humans are in the same place at the same time, the natural behavioral patterns of sea otters can be distrupted. Locations like harbors and bays, with easy access to the ocean and calm, protected conditions, are especially alluring to both recreationists and marine wildlife. Sea otters are very charismatic and viewing and/or photographing them is often a primary goal of marine recreationists. Kayakers, stand-up paddlers, scuba divers, ecotour operators, and others are often unaware that the manner in which they behave near otters can disturb important behavioral patterns and result in wasted energy, increased stress, and potentially pup abandonment.
Why is disturbance so harmful to sea otters specifically?
Because sea otters don’t store energy in the form of fat, they are dependent on a delicate balance of energy income in the form of prey and energy expense from activities such as swimming back and forth to foraging areas, social interaction, fur maintenance, and caring for their pups. Like some of us, they live “paycheck to paycheck,” struggling to balance that energy income versus expense equation every day. Swimming and diving to avoid watercraft that approach too closely or too aggressively results in an additional energy expense burden. If this results in an energy deficit, the sea otter must either find more prey to eat or risk losing body condition, which is elemental to good health, disease resistance, reproductive success, and survival.
More people often means more sea otter disturbance
Perhaps most importantly, at sites designated as “Disturbance Hot Spots”—Moss Landing, Monterey, and yes, Morro Bay ─ a high density of recreationists means a higher disturbance frequency. A sea otter off the Big Sur coast that dives to avoid people once per month is not going to suffer the same cumulative effects as otters at these high-traffic sites where our data show sea otters may be disturbed an average of six times each day and as many as twenty times!
The sea otters of Morro Bay have become quite habituated to human presence in a relatively short amount of time. If an otter does not swim away when a kayak comes within fifteen, ten, or five yards of it, is coming this close still wrong? We have yet to dig into this question from a scientific perspective, but it is probable that habituation’s apparent reprieve from disturbance comes at a price—cross-exposure to zoonotic diseases or increasing aggressive encounters are some examples. In an ever more crowded world, we need to do what we can to preserve the wildness of these animals for their sake and ours.
Why do we need guidelines?
Guidelines help people make recommended choices. At the foundation of Sea Otter Savvy’s guidelines are two basic objectives:
- Increase compliance with the laws protecting sea otters from harassment
- Reduce chronic, potentially harmful, disturbance.
Our program is founded on the basic assumption that most people do not wish to inflict harm on sea otters. These guidelines, especially when accompanied by information about why sea otters are vulnerable to the effects of human disturbance, encourage people to choose behavior that promotes stewardship over disturbance.
How are guidelines developed?
The process of deciding what guidelines are necessary, practical, and effective is a rocky road. Setting minimum distance recommendations for sea otters is especially challenging as sea otters in different locations have different thresholds for disturbance. (Think back to the sea otter in Big Sur versus the sea otter in Morro Bay, for example.)
Specific location attributes need to be considered
Other factors—location features, human psychology—play an important role in determining effectiveness. For example, kayaks and stand-up paddleboards launching from one of Morro Bay’s most popular access points, Coleman Beach, may be within fifty yards of resting sea otters as soon as they hit the water. Even if they have the best of intentions to avoid sea otters, establishing a distance guideline of fifty yards would set paddlers up for failure.
Creating a guideline that is impractical given the specifics of a location, may create a lack of trust and compliance in paddlers that renders the guideline ineffective. The context of each encounter also needs to be taken into account. Foraging sea otters may pop up next to a kayak well within even the narrowest distance guideline. As long as the paddler does not pursue the forager, or move between a mother sea otter and her pup, they are still complying with the spirit of the guidelines, which is to avoid disrupting natural behavior.
Who gets a say?
Input from the community, stakeholders, and experts, together with the most recent science, are at the foundation of Sea Otter Savvy’s guidelines. We will continue to evolve them to be as effective as possible at reducing human disturbance to sea otters. Despite the complex process behind their development, our guidelines are simple rules of behavior that anyone can follow. These guidelines will not only help people “respect the nap,” they will also enhance everyone’s wildlife experience by protecting the vital natural behaviors of our neighborhood sea otters.
Sea Otter Savvy Guidelines
Maintain a respectful distance from all wildlife.
Specific distance recommendations are hard to make, since wildlife react differently in different places and situations. However, we recommend staying at least five lengths of your kayak (around twenty yards.) away from all marine wildlife. When in doubt, give them extra space!
Avoid approaching sea otters directly.
Maneuvering your craft directly at an otter or raft of otters can be perceived as much more threatening than passing by parallel or obliquely, while keeping a steady pace.
Do not encircle sea otters with watercraft—they will feel trapped.
If someone else is already watching the sea otters, wait your turn before approaching and stopping at a respectful distance away.
Noisy paddlers, loud music on boats, and even noisy observers on shore, are much more likely to disturb sea otters than quiet wildlife watchers.
Most importantly, pay attention.
Keep a watchful eye on the sea otters for changes in behavior. If they raise their heads and look at you, they are warning you that you are getting too close. Their next step might be to dive and swim away.
We can all help sea otters by watching them responsibly
Every business operator in Morro Bay that caters to people visiting the waters of the bay has an obligation to promote stewardship by sharing guidelines for protecting wildlife. All of us can help! Paddlers in Morro Bay are visible to locals and visitors alike. Many will watch and look to others to show them how to behave around wildlife—you are their role model! Encourage people to think about the needs and well-being of sea otters when they are viewing them. Try leaving your smart phone behind when you paddle. This will inspire you to enjoy your experience mindfully and avoid the temptation to get that selfie with wildlife! Armed with a little information, we can share the coastal environment respectfully and peacefully with sea otters!
Protecting sea otters is the law
When we understand the needs of sea otters, we can watch them from a respectful distance without disturbing them, and encourage others to do the same. Federal and state law and a number of local laws and regulation also protect sea otters from harrassment. Harassing and disturbing sea otters and other marine mammals, even when unintentional, violates the law.

Note: The guidelines discussed here pertain primarily to people using small craft (kayaks, SUP, electric boats). For those using larger, motor-powered craft in sea otter habitat find more information on our website.
