Nothing, really. It’s just that Kevin, the creator of Lion Den, is a former lion tamer and wildlife safari leader—and has always loved lions. Back in the olden days of the internet, he chose “” as the domain name for his mixed-use site of student resources, circus animal facts, and safari stories—and the name stuck!

It’s what you do to get ready for what will probably be the most rigorous course of your life—A&P. The Pre-A&P resources in the Lion Den specifically serve Kevin’s online Pre-A&P course, but any student can use them to review before taking A&P—or to catch up with basic science while taking A&P.
