Besides bivalves, what other specific invertebrates are listed as part of the walrus menu?
Answer
Sea cucumbers, snails, crabs, and starfish
While bivalve mollusks dominate the diet, walruses are recognized as opportunistic feeders, meaning their menu adapts based on local availability on the seabed substrate. Beyond clams and mussels, their diet includes several other types of invertebrates found in the Arctic seabed. These additions specifically include sea cucumbers, which can be plentiful in some regions, as well as snails, crabs, and starfish. Furthermore, the diet extends to include tunicates and polychaete worms, demonstrating a broader reliance on the entire range of benthic life.
