A commuter ferry traveling from Seattle to Bainbridge Island across Elliott Bay struck a humpback whale Tuesday night, according to reports.

The ferry struck the whale about three minutes into the 10-mile trip as it surfaced for air, and the animal went down into the water, Seattle's Q13 FOX reported.

"Everyone watched in horror," one passenger of the WSF Wenatchee, operated by Washington State Ferries, told the Seattle Times.

The crew, at first, thought the ferry had struck a log, but later saw the whale bleeding near the side of the boat.

“The whale surfaced after being struck and [was] gushing a lot of blood. It surfaced a few more times before sinking,” another passenger told the Times.

The whale broke about five feet from the ferry before it was hit, a Washington State Ferries spokesperson said, according to Q13.

The Coast Guard was searching for the injured animal. Witnesses told the Times the whale looked like it could be dying.
