Ronan, a sea lion, has now become the first non-human mammal who can keep up with a beat. The ability to keep a track of beat was previously found only in birds like parrots that can mimic the human voice.
Scientists from University of California, Santa Cruz, have taught Ronan to bob her head according to a rhythm.
What makes Ronan's ability special is that sea lions don't make a lot of sounds and the capacity for keeping the beat requires the knowledge of many different sounds.
