Point Defiance Zoo & Aquarium on Instagram: "Wonderful walrus sounds! 🎵 Walruses are social animals and are known for their unique and loud vocalizations. They produce growls, roars, whistles, grunts, barks, and more for communication. A male walrus roar can reach levels of up to 120 decibels, making them one of the loudest sounds produced by marine mammals. #walrus #pointdefiancezoo #animalcare"
