A few years ago, marine biologist Kyle Van Houtan spotted an online video that he couldn't quite believe. It showed a young great white shark, about five-feet long, swimming just off a pier in Central California.
"Our initial reaction was that it can't be true," Van Houtan says. "We know that they're in Southern California and Mexico, not in Monterey."
When they're young, white sharks typically live in the warm waters of Southern California, hundreds of miles from the cold, rough surf up north off Monterey.
