The estimated 2,000-pound Steller sea lion nicknamed 'Chonkers' is hanging out at San Francisco's Pier 39 and drawing fans from across the country. The massive mammal made waves about a month ago when he hauled himself onto the pier and decided to stay. While California sea lions typically crowd the area, ‘Chonkers’ quickly stood out for his massive size. He is one of at least two Steller sea lions recently spotted in the bay. The animal is more commonly found in the colder waters of Alaska and the Pacific Northwest, making sightings in the Bay Area less common.
