As a marine biologist with a focus on cetacean behavior and ecology, I have spent considerable time studying the various species of whales and their dietary habits. When it comes to the question of whether orcas, or killer whales, eat walruses, it's important to understand the different ecotypes of orcas and their respective diets.
Orcas are apex predators found in oceans all around the world. They are known for their sophisticated hunting techniques and diverse diets, which can vary greatly depending on the region and the specific group of orcas. There are two main types of orcas: resident and transient.
Resident orcas are often associated with a more fish-based diet. They are known to consume a wide variety of fish, including salmon, herring, and mackerel. There is no evidence to suggest that resident killer whales eat marine mammals, which would include walruses. This is a significant point, as it sets them apart from the transient orcas.
Transient orcas, on the other hand, are more specialized hunters of marine mammals. They are also known as Bigg's orcas after the researcher Michael Bigg, who identified them as a separate type. Transient orcas spend a significant portion of their time foraging, and their diet primarily consists of marine mammals. This includes seals, sea lions, and even other cetaceans such as porpoises and smaller dolphins. The statement that transient orcas eat marine mammals including seals, sea lions, walruses, baleen whales, other toothed whales, and occasionally sea otters is accurate. However, it's important to note the context and the frequency of such occurrences.
Walruses are large, formidable animals that are not an easy prey. While transient orcas are known to be opportunistic predators and have been observed attacking larger marine mammals, the predation on walruses is not a common event. It would likely happen under specific circumstances, such as when a walrus is isolated from its group, is injured, or is particularly vulnerable.
In addition, the success rate of such hunts would be influenced by several factors, including the size and experience of the orca pod, the behavior of the walrus, and environmental conditions. Walruses have been known to defend themselves effectively using their large tusks, which can deter orcas from attacking.
In conclusion, while it is biologically possible for orcas to eat walruses, especially transient orcas that are known to prey on a variety of marine mammals, it is not a frequent occurrence. The diet of orcas is highly adaptable and can change based on the availability of prey and the specific hunting strategies of different orca groups. Understanding these nuances is crucial for appreciating the complex ecological roles that orcas play in marine ecosystems.

There is no evidence of resident killer whales eating marine mammals. ... Transient whales spend about 90% of daylight hours foraging. They primarily eat marine mammals including seals, sea lions, walruses, baleen whales, other toothed whales, and occasionally sea otters.
