Ronan the sea lion knows how to keep a beat. Just turn on some disco or some late 90s Backstreet Boys, and she'll nod her head and keep time. Incredible.
Here's what the University of California Santa Cruz's Pinniped Lab had to say about Ronan:
One of our resident sea lions, Ronan, is the first non-human mammal shown able to find and keep the beat with musical stimuli. This challenges earlier evidence from humans and parrots suggesting that complex vocal mimicry is a necessary precondition for flexible rhythmic entrainment.
All I know is that she's a much better dancer than I am.
