Don’t mess with the beach master. A male Australian sea lion basks in the sun with one of his mates on Seal Beach, Kangaroo Island, Australia. This particular beach is home to over 1,000 sea lions, comprising 1/7 of the entire population! Each of the males can maintain a harem of up to 30 females. In order to get up close to the sea lions, you need to book a guided tour with a conservation park ranger; many tours are run throughout the day.
