Could a whale really swallow a human? A marine scientist explains

A whale scientist says a sperm whale could fit a human inside. But this has never happened. It would be unrealistic.

The new film Whalefall imagines a diver swallowed by a sperm whale with 60 minutes of oxygen to escape. Could this actually happen?

Dr Vanessa Pirotta is a whale scientist at Macquarie University. She says a sperm whale's mouth is large enough for a human to fit inside.

A human could potentially be pulled down the throat. The movie's premise, however, has major problems.

Sperm whales hunt at depths of at least one kilometre where pressure would kill a human instantly. The whale would sense the diver's metal and plastic scuba gear.

It would know it is not food. Most importantly, no human has ever been swallowed by a whale.

These animals aren't targeting people. They're hunting their natural prey.

Pirotta is glad the film exists. It sparks public curiosity about whales and ocean science.

Why it mattersThe question separates movie fiction from real marine biology. It helps audiences understand how whale behavior actually works. This is better than accepting Hollywood assumptions.

AustraliaAustralian marine research into whale behaviour is deepening our understanding of these animals in our waters; popular films drive wider public interest in ocean conservation.
