What Do Walruses Eat?

Walruses are large marine mammals that primarily feed on benthic invertebrates found on the ocean floor. Their main food source is clams, which they locate using their highly sensitive whiskers. Walruses use their tusks to break open the shells of clams and other shellfish, allowing them to access the nutritious meat inside. In addition to clams, walruses also consume a variety of other benthic invertebrates, such as worms, snails, and crustaceans.

While clams make up the majority of a walrus's diet, they are also known to eat fish, seals, and even small whales on occasion. Walruses are opportunistic feeders, meaning they will consume whatever food source is readily available to them. However, their preference for clams and other benthic invertebrates is clear, as these foods are rich in nutrients and provide the walruses with the energy they need to survive in their cold, harsh environment.

Walruses are capable of diving to great depths in search of food, with some individuals reaching depths of up to 300 feet. Their ability to hold their breath for long periods of time allows them to forage for food on the ocean floor for extended periods. In addition to their impressive diving abilities, walruses also have a keen sense of smell, which helps them locate food sources in the murky waters of the Arctic and sub-Arctic regions where they live.

In order to protect their food sources and ensure a stable food supply, walruses are highly territorial animals. They will defend their feeding grounds from other walruses and predators, using their tusks and sheer size to intimidate potential threats. This territorial behavior is crucial for the survival of walrus populations, as competition for food can be fierce in their harsh environment.

Overall, clams are the main food source of walruses, providing them with the nutrients and energy they need to survive in their icy habitat. While walruses are capable of consuming a variety of other foods, their preference for benthic invertebrates is clear, showcasing their adaptation to their unique environment.
