As a marine biologist with extensive fieldwork on the feeding habits of marine mammals, I can provide a detailed account of how killer whales, also known as orcas, consume their food.
Orcas are apex predators, which means they sit at the top of the food chain and are not preyed upon by any other animals, except for humans. Their diet is diverse and includes a range of marine life. Here's how they typically eat their prey:
1. Hunting Techniques: Orcas employ a variety of hunting strategies depending on the prey. They are known to work cooperatively in pods, using coordinated attacks to isolate and capture their food.
2. Feeding on Fish: When hunting schools of fish, orcas may use a method called "herring herding," where they create a tight ball of fish by releasing bubbles and sounds. Once the fish are concentrated, the orcas take turns swimming through the ball, picking off individual fish with their sharp teeth.
3. Feeding on Squid and Octopuses: For cephalopods, orcas may use a technique where they forcefully slap the water with their tails, stunning the prey before capturing it.
4. Feeding on Marine Mammals: When hunting marine mammals like seals, orcas may use a "carousel feeding" method. They create waves to dislodge the seal from the ice, then take turns lunging out of the water to snatch the seal.
5. Feeding on Sharks: Orcas are known to target sharks by flipping them upside down, a process known as "tonging." This incapacitates the shark by disrupting its ability to swim and makes it easier for the orca to remove and consume the shark's liver, which is rich in nutrients.
6. Social Learning and Innovation: Orcas are highly intelligent and have been observed to pass on hunting techniques from one generation to the next. This social learning allows them to adapt to different prey and environments.
7.
Diet Variability: The diet of orcas can vary by region. Some populations may specialize in hunting specific prey, while others have a more generalist diet.
8.
Echolocation: Orcas use echolocation to locate and identify their prey in the water. They emit sounds and listen for the echoes to determine the location and distance of objects.
9.
Physical Adaptations: Their physical features, such as their conical teeth and powerful jaws, are well-suited for gripping and tearing apart their prey.
10.
Energy and Nutrition: Orcas require a substantial amount of energy to sustain their active lifestyle. They consume enough food to meet their caloric needs, which can be several hundred pounds of food per day.
Orcas are fascinating creatures with complex social structures and behaviors. Their feeding habits are just one aspect of what makes them such intriguing subjects for study.

Orcas are apex predators, at the top of the food chain. No other animals (except for humans) hunt orcas. Killer whales feed on sea birds, squid, octopuses, sea turtles, sharks, rays and fish. They also eat most marine mammals, such as seals and dugongs.Nov 20, 2014
