Harold “Wes” Pratt is a scientist with Mote Marine Laboratory’s Center for Shark Research, Summerland Key, Florida. His professional career studying the biology of white, blue, mako, nurse and sandbar shark has led to a current focus on the behavior of sharks as it relates to mating success. Recent efforts have revealed previously unknown and unexpected facets of complex behaviors in these fascinating but poorly understood reef predators. The author of numerous scientific articles, his work has been featured in four National Geographic Magazines and many documentary television programs. Wes is a diver, photographer, and current Coast Guard licensed Captain (100 tons).
