The world's biggest iceberg — a wall of ice the size of Rhode Island — is lumbering toward a remote island off Antarctica that's home to millions of penguins and seals.

The iceberg could be around 15m (49ft) tall, meaning the penguins could not climb it. “There’s an ice crack, so they might have been able to dive through it,” he says.

Some penguins can grow up to 45 inches tall and weigh up to 100 pounds, so when a group gathers on an iceberg, it’s no surprise that the added weight can cause it to tip.

You’ll never forget one of the world’s greatest wildlife encounters – but nobody tells you penguins have stinky feet, not happy feet.
