More than 300 manatees swam into Three Sisters Springs, located in the Crystal River National Wildlife Refuge, all at once, setting a new record for the area and causing what the U.S. Fish and Wildlife Service called “a traffic jam.” The springs are the spot for Florida’s manatees all winter, because they’re warmer than the open water and not infested with dangerous boats.
