A runaway penguin has been found safe in Japan nearly two weeks after she first went missing, having paddled 45 kilometers (28 miles) during a typhoon in a survival story her keeper called “miraculous.”

While taking a dip in the ocean to avoid heatstroke, Pen suddenly became agitated and swam through a hole in her enclosure out into open waters. Her escape left Imai wracked with worry and guilt.

African penguins can swim up to 40 kilometers (25 miles) a day, he said, but in captivity, their muscle mass decreases. Pen had never swum in the sea before visiting that beach.

A lucky break would keep Pen safe.

A powerful typhoon called Shanshan brought high winds and torrential rain to the country at the end of August, killing at least six people, displacing millions, knocking out power and disrupting air travel.

But, amid the destruction, the typhoon was a boon for little Pen, Imai said. With no boats able to operate, Pen avoided collisions and getting caught in fishing nets. The record rainfall provided a reliable source of hydration and cooling.

“She survived because of the typhoon,” Imai said. “It was almost miraculous timing.”

Because of the typhoon, Gekidan Penters wasn’t initially able to send out rescue boats to search for Pen, so it was even more surprising when on Sunday someone spotted her swimming near a beach about 8 miles from where she first went missing. It was just 10 minutes from the facility where she usually lives.

“When we first received the report, I couldn’t believe there was really a penguin,” Imai said. “It was a huge relief.”

Pen had no injuries and was in good physical shape.

She also passed “substantial droppings,” Imai said, which means she must’ve found something to snack on during her journey – likely fish or crab, her keeper guessed, though Pen had never eaten live fish before.

He added, “it’s nothing short of a miracle.”
