It’s vital for walruses to eat these invertebrates. What they eat affects their health and energy. As the seasons change, walruses change how they hunt to find food.
Knowing what walruses like to eat helps us understand how they survive. They can live in different places because they adapt their eating habits.
| Component | Description | Importance |
|---|---|---|
| Clams | Soft-bodied bivalves found in abundance | Primary source of nutrition |
| Worms | Includes various species living in the ocean floor | Rich in protein |
| Snails | Common prey item, providing essential fats | Supports energy needs |
