Yes, you read it correctly.
Who knew that a walrus could play a double bass? Well, in fact, they can’t.
But they do communicate with sound. They have quite the repertoire. You can read more about this aspect of ‘walrus-ness’ here.
So what is it about walruses and double bass? At a zoo in Tacoma, one of the workers is a bass player. She plays her bass for the walruses. And they seem to like it. OR perhaps not? It is not clear to me if they are happy to hear her or unhappy. See what you think when you watch the video.
