What is the main food of walruses?

Walruses are carnivorous marine mammals that primarily feed on benthic invertebrates, such as clams, mussels, and snails, found on the seafloor. They have specialized tusks and powerful jaws to dig up and crush these hard-shelled prey. Walruses are known to dive deep into the ocean, sometimes reaching depths of several hundred feet, in search of their preferred food sources.
