The Art of Food Storage
Sea otters are skilled foragers, using their nimble hands and sensitive whiskers to search for prey in the kelp forests and ocean floor. Once they’ve caught their food, they use their teeth and paws to prepare it for storage. This can involve cracking open shells, removing spines from sea urchins, or simply cleaning their catch to remove any dirt or debris. The prepared food is then placed in the loose pouch of skin under their forearms, where it’s kept safe and secure until the otter is ready to eat.
The types of food stored by sea otters can vary depending on the location and the time of year. In general, however, they tend to cache sea urchins, crabs, and other small marine animals. These foods are rich in nutrients and energy, making them the perfect choice for sea otters, which need to fuel their high metabolisms in order to stay warm and active in the cold ocean water.
The Benefits of Food Storage
So why do sea otters store food in the first place? The answer lies in the benefits of this behavior, which are numerous and significant.

This is particularly important for female sea otters, which need to nourish their pups and keep them warm in the cold ocean water. The ability to store food on their bodies is a vital component of sea otter survival, and is a key factor in their success as a species.
The Role of Fur in Food Storage
Sea otters’ fur is one of their most distinctive and remarkable features, and plays a crucial role in food storage. The fur is incredibly dense, with up to 1 million hairs per square inch, making it the thickest fur of any mammal. This density helps to keep the otter’s skin dry and warm, even in the cold ocean water, and also provides a layer of protection for their stored food. The fur is also very clean, with sea otters spending a significant amount of time grooming themselves to remove any dirt or debris.
The cleanliness of their fur is essential for food storage, as any dirt or bacteria could contaminate their food and make them sick. By keeping their fur clean, sea otters can ensure that their stored food remains fresh and safe to eat. This is particularly important, as sea otters have a high metabolism and need to eat frequently to maintain their energy levels. The combination of their dense fur and careful grooming habits makes sea otters one of the cleanest animals in the ocean, and allows them to thrive in their environment.
Other Unique Adaptations
In addition to their remarkable fur and food storage abilities, sea otters have several other unique adaptations that help them survive in their environment. Their agile hands, for example, are perfectly suited for foraging and manipulating food, and are also used for grooming and cleaning their fur. Their sensitive whiskers, meanwhile, help them detect prey in the dark or murky waters, and also provide a sense of spatial awareness, allowing them to navigate through the kelp forests with ease.
Sea otters also have an incredibly high metabolism, which helps them stay warm in the cold ocean water. This is essential, as they have a very thin layer of blubber, and rely on their fur and metabolism to keep them warm. The combination of their high metabolism, dense fur, and agile hands makes sea otters one of the most well-adapted animals in the ocean, and allows them to thrive in even the most challenging environments.
The Significance of Food Storage While Diving
One of the most impressive aspects of sea otter behavior is their ability to store food while diving.

The ability to store food while diving is a vital component of sea otter survival, as it enables them to take advantage of the abundant food sources available on the ocean floor.
By caching their food, sea otters can also reduce the need for repeated dives, which can be energetically expensive and increase their risk of predation. This is particularly important for female sea otters, which need to balance their energy expenditure with the need to nourish their pups and keep them warm. The ability to store food while diving is a key adaptation that allows sea otters to thrive in their environment, and is a testament to their remarkable flexibility and resourcefulness.
Using Stored Food
So how do sea otters use the food they’ve stored on their bodies? The answer is simple – they eat it. Sea otters typically eat their stored food while floating on their backs, using their paws and teeth to manipulate their catch. They may also use rocks to crack open shells or remove spines from sea urchins, and will often use their fur to wipe their paws and faces clean after eating.
The ability to use stored food is essential for sea otters, as it allows them to maintain their energy levels and stay warm in the cold ocean water. By having a steady supply of food available, they can avoid the need for repeated foraging trips, which can be energetically expensive and increase their risk of predation. The combination of their stored food and high metabolism makes sea otters one of the most successful predators in the ocean, and allows them to thrive in even the most challenging environments.
