MIAMI, Florida (CNN) -- A woman on a boat died after a spotted eagle ray leaped from the water off the Florida Keys Thursday and struck her, officials said.

The dead spotted eagle ray lies on the deck of a boat in Florida.

The force of the blow pushed the woman backward and she died when she hit her head on the boat deck, officials said.

"It's just as freakish of an accident as I have heard," said Jorge Pino of the Florida Fish and Wildlife Conservation Commission. "The chances of this occurring are so remote that most of us are completely astonished that this happened."

The commission identified the woman as Judy Kay Zagorski, 57, of Pigeon, Michigan.

The woman was seated or standing in the front of the boat as her husband piloted the vessel at about 25 mph out of a channel, Pino said. "The ray just actually popped up in front of the vessel," he said. "The father had not even a second to react. It was too late. It happened instantly and the woman fell backwards and, unfortunately, died as a result of the collision."
