“It’s an honor and a privilege to work with the largest living reptile and largest terrestrial predator on the planet,” Robert tells me in the singsong tone of his television-ready family. “An awesome animal that roamed the primeval landscape for millions and millions of years.”

Daisy’s sawtooth tail whips the prone boy to the left. “The jaw pressure of the crocodile is incredible—3,000 pounds per square inch!”

Daisy’s tail whips him to the right. “I so admire the crocodile’s ability to kill with just its teeth. It’s quite amazing!”

Robert’s 16-year-old sister, Bindi, looks on solicitously. An actor, singer, game show host and, last year, a People cover girl, she’s confirming Daisy’s gender by inserting a finger into its cloaca and feeling around for genitalia. “It’s a girl!” she says. Her smile conveys a disarming buoyancy. “Here’s an animal that many people think is just a stupid, evil, ugly monster which kills people. That’s so not true!”
