When sharks attack, it’s usually because of seals
A couple of shark encounters scared beach goers in Orleans, Massachusetts and Santa Cruz, California this weekend. No one was hurt, but both sharks were identified as Great Whites and each was at least 12 feet long. Experts say the sharks were hunting seals, not people. Ed Schultz talks to marine biologist and shark expert Chris Wojcik about what's attracting sharks to the beaches on both coasts.
