Born in Phoenix, Arizona, Sneed grew up in Santa Barbara, CA. After his parents divorced, he split his time between Santa Barbara, Woods Hole, Massachusetts, and Pensacola, Florida, where his biologist father lived. His love of travel and biology have guided his career. He graduated with Honors in marine biology from Berkeley, but immediately launched his writing career. His first thirty or so books all focused on science and the environment, and he traveled widely to research them. More recently, he's focused his efforts on fiction. His newest, Double Eagle, is a thriller inspired by a summer he spent with his father on Dauphin Island, Alabama.
Sneed Collard's first book,Sea Snakes, was published in 1993, and since then he has published over forty-five books for children, including the award winning A Platypus, Probably; Beaks!; Animal Dads;One Night in the Coral Sea; and The Prairie Builders Reconstructing America's Lost Grasslands, winner of 2006 AAAS/Subaru/Science Books & Films Prize for Excellence in Science Books.
