How Inky the Octopus Escaped a New Zealand Aquarium Through a Drainpipe
In 2016, staff at the National Aquarium of New Zealand in Napier arrived one morning to find their octopus tank completely empty. Inky, a common New Zealand octopus, had exploited a lid left slightly open overnight, crossed the aquarium floor and squeezed through a narrow drainpipe — depositing himself into the waters of Hawke’s Bay. He was never seen again.
“When we came in the next morning and his tank was empty, I was really surprised,” said Rob Yarrell, national manager of the National Aquarium of New Zealand, per The Guardian. “The staff and I have been pretty sad. But then, this is Inky, and he’s always been a bit of a surprise octopus.”
How Inky’s Escape Happened
The escape route was straightforward but required remarkable physical ability. Staff believed Inky climbed out through the gap in his tank lid, made his way across the aquarium floor and located a drainpipe. He then squeezed his entire body through it, traveling roughly 50 meters until the pipe deposited him into the ocean.
Another theory suggested he squeezed into an open pipe at the top of his tank, which led under the floor to the drain. Either way, Inky vanished into the Pacific and no attempt was made to retrieve him.
Octopuses do not have bones, relying instead on a soft, muscular structure supported by a hydrostatic system. This allows them to squeeze through openings sometimes no larger than their own eye. Their boneless design also enables unique movement — from crawling along the ocean floor to jetting through water by expelling it rapidly from their bodies.
Experts Say Curiosity Drove Inky, Not Distress
Aquarium officials were not entirely surprised by the escape, noting that octopuses are known for their curiosity, problem-solving abilities and capacity to slip through extremely small spaces.
Yarrell put it simply: “Octopuses are famous escape artists. But Inky really tested the waters here. I don’t think he was unhappy with us, or lonely, as octopus are solitary creatures. But he is such a curious boy. He would want to know what’s happening on the outside. That’s just his personality.”
Officials Believed There Was No Foul Play in Inky’s Disappearance
Reiss Jenkinson, exhibits keeper at the National Aquarium, said he was absolutely certain Inky was not “taken” or “stolen.”
“I understand the nature of octopus behavior very well,” he said. “I have seen octopus on boats slip through bilge pumps. And the security here is too tight for anyone to take Inky, and why would they?”
Inky did leave one thing behind — his tankmate, Blotchy. “We have another octopus, Blotchy, but he is smaller than Inky, and Inky had the personality,” Yarrell said.
What This Means for Biologists
As Yarrell said: “He managed to make his way to one of the drain holes that go back to the ocean, and off he went. Didn’t even leave us a message.”
Inky’s escape became a viral sensation, but the facts confirmed by aquarium staff and marine biologists are more remarkable than the memes. A single gap in a tank lid gave a boneless, curious animal everything it needed to find its way back to the ocean.
