Can a Whale Really Swallow a Scuba Diver?

Can a Whale Really Swallow a Scuba Diver?

Whalefall is in theaters, and if you dive, someone is about to ask you this. Maybe it's already happened.

So here's the straight answer, from the people who actually study whales.

The short answer

Almost certainly not.

A whale can end up with a diver in its mouth. That has happened. But a whale swallowing a diver for good? Only one kind of whale even has the plumbing for it, and one expert called the odds "a billion to one thing."

What happens in the movie

In Whalefall, Austin Abrams plays Jay Gardiner, a diver searching for his late father's remains. A sperm whale swallows him, and he has about an hour to find a way out.

It's fiction, based on Daniel Kraus's 2023 novel. Coverage of the film says Kraus drew on real whale encounters for the story, including one involving a lobster diver in Massachusetts.

The real story: Michael Packard

In June 2021, commercial lobster diver Michael Packard, then 56, was about 45 feet down off Provincetown on Cape Cod. He felt a huge bump, and everything went dark.

He first thought a shark had him. Then he realized he couldn't feel any teeth, and there was almost no pain. He was inside a humpback whale's mouth.

By his estimate, he was in there for 30 to 40 seconds. He could keep breathing because he still had his breathing gear. Then the whale rose to the surface, shook its head, and spat him out. His crewmate pulled him from the water.

Packard went home from the hospital the same day with bruises and soft tissue damage. No broken bones.

So what actually happened?

Whale experts said it was almost certainly an accident. Humpbacks feed by lunging with their mouths wide open, scooping up huge amounts of water and the fish in it. One researcher thought the whale was likely chasing sand eels.

Packard just happened to be in the wrong spot. A whale expert from the nonprofit Ocean Alliance compared it to a cyclist with their mouth open accidentally taking in a fly. The whale didn't want him there.

Another expert, from Whale and Dolphin Conservation, put it simply: he was engulfed, not swallowed.

Why a humpback can't swallow you

A humpback's mouth is huge. Its throat is not.

The throat is roughly the size of a human fist, and it only stretches to about 15 inches across. Humpbacks are baleen whales. They have no teeth. They strain tiny fish and krill through bristly plates and swallow the small stuff.

A person simply doesn't fit down there. A whale that gets one in its mouth by mistake has one move left, and that's to spit it out.

What about sperm whales?

This is where the movie gets its premise. Of about 90 known whale species, sperm whales are the only ones with a throat big enough to technically swallow a person. They eat large prey like giant squid.

But sperm whales live mostly in the open ocean and regularly dive deeper than 10,000 feet. A researcher with the Zoological Society of London's strandings program pointed out that most people will never see one in their lifetime. That's a big part of why a real-life Whalefall is so unlikely.

It's happened again, and nobody got swallowed

On February 8, 2025, a 24-year-old kayaker named Adrián Simancas was paddling in the Strait of Magellan off Chile when a humpback briefly took him into its mouth. His father, in a pack raft nearby, caught it on video. The whale spat him out almost immediately, and he was unharmed.

National Geographic also lists a tour operator caught in a feeding humpback's mouth in South Africa in 2019. These cases are accidents, and in each one the person survived.

What this means when you're diving

You don't need to worry about being a whale's lunch. You are not on the menu.

But a feeding whale is a big, fast animal that isn't watching for you. A few common sense habits go a long way:

  • Give whales plenty of room. Experts recommend keeping your distance and avoiding anything that startles them.
  • If you see signs of feeding, like a swirling ball of baitfish or diving birds, don't swim into the middle of it.
  • Always dive with a buddy or a surface crew who knows your plan. Packard's crewmate was the one who got him out of the water.

Quick answers

Can a whale swallow a scuba diver?

Almost certainly not. Only sperm whales have a throat big enough, and an encounter like that is extremely unlikely.

Did a diver really get swallowed by a whale?

A diver was taken into a humpback's mouth for about 30 to 40 seconds and spat out. Experts say that's engulfed, not swallowed.

Is Whalefall a true story?

No. It's a fictional thriller based on a novel, though real encounters helped inspire it.
