Scientists at the University of St. Andrews taught three young gray seals to sing, literally.

Seals, which generally bark, and other marine mammals are known for some of the sounds they make. Whales sing, dolphins click, penguins peep and walruses bellow.

Researchers, though, were able to train the three young seals to bark out the notes to the opening bars of the theme from “Star Wars” and “Twinkle, Twinkle Little Star.”

The research is published in the journal Current Biology.

It's not just that teaching a seal to sing is an interesting project, St. Andrews scientists said they wanted to learn more about how seals communicate with each other, according to Smithsonian magazine. Knowing how seals communicate in the wild could become important in the future to conservation efforts.
