Teenager pleas guilty to attacking California sea lion in viral video

Tyler Muehl, 18, could face a year in prison for kicking marine animal four times on La Jolla coast

An 18-year-old California man has admitted he kicked a sea lion in a video that went viral recently - while referring to himself by the name of an Ultimate Fighting Championship (UFC) competitor - and has pleaded guilty to a federal crime.

Tyler Muehl, of San Diego's La Jolla neighborhood, faces up to a year in prison and a $100,000 fine after acknowledging in court on Thursday that he violated the Marine Mammal Protection Act's prohibition on harassment of wildlife, federal prosecutors said in a statement.
