The National Zoo, which includes about 1,500 animals on 163 acres in Washington’s Rock Creek Park, typically closes only for Christmas. Through the first 10 months of 2018, the zoo drew 1.3 million visitors. If a continuing shutdown forces closure of the zoo to the public, St.Thomas said, it will still be fully staffed so that no animals are placed in jeopardy.
