This set of five stamps features realistic images of five species that inhabit American waters: mako shark, represented by a shortfin mako; thresher shark, on the stamp a pelagic thresher; great white shark; whale shark; and hammerhead shark, on the stamp a scalloped hammerhead. One of the most feared of all living creatures, sharks are widely used in popular media, one of the most prominent ever being the 1975 film, Jaws. Despite popular portrayals, out of more than 470 species, only four have been involved in a significant number of fatal, unprovoked attacks on humans. The only one depicted on any of the new stamps is the great white shark.
