King walruses are adept divers, capable of reaching depths of up to 80 meters (262 feet) and staying submerged for as long as 30 minutes. Their bodies are adapted to conserve oxygen during dives, allowing them to reach benthic prey that resides on the ocean floor.
Social Behavior
These marine mammals have also developed social behaviors that enhance their survival. King walruses often form large groups, known as herds, which provide protection against predators like polar bears and killer whales. Social bonds within these herds are crucial for communication, mating, and rearing young.
Diet and Feeding Habits
The diet of the king walrus primarily consists of benthic invertebrates, which they find on the ocean floor. Their feeding habits are adapted to the availability of prey in their Arctic habitat.
Primary Diet
King walruses feed on a variety of bottom-dwelling invertebrates, such as:
- Clams
- Mollusks
- Worms
- Shrimp
They use their sensitive vibrissae to locate these prey items in the sediment, often sucking them out of their shells with a powerful suction force.
Feeding Techniques
Walruses employ specialized feeding techniques to access their prey:
- Suction Feeding: Using their powerful tongues, walruses create a vacuum to extract prey from shells or burrows.
- Foraging: They dig into the seafloor with their tusks to uncover buried food sources.
The king walrus's diet is highly dependent on the availability of prey in their region, and they may travel long distances to find suitable feeding grounds.
Social Structure and Behavior
The social structure of king walruses is complex and plays a significant role in their survival and reproduction. Understanding their social behavior is essential for conserving these fascinating creatures.
