In response to a viewer’s question, Erin Lundy, a mammologist at the Aquarium of the Pacific in Long Beach, California, asked Cain, a resident sea lion to roar at the top of his lungs. Cain obliged with a big bark. Another mammologist then asked sea lion Parker to give his loudest try. Parker’s voicing was good but a bit choppy. Erin then turned a third sea lion named Harpo who immediately blew the other pinnipeds away. Of course, Harpo’s yelling got the other two going leading to an utter cacophony of sea lion sound.
