This isn't the Polks' first tangle with a big shark. The two men have three combined world records from the International Land-Based Shark Fishing Association. Earnie caught an 11-foot-2-inch, 674-pound shortfin mako in 2009 and an 11-foot-9-inch, 928-pound tiger shark in 2010. Joey beat Earnie's record a month later with a 12-foot-9-inch, 949-pound tiger shark. They claim to have caught more than 300 sharks from the shore in 2013 alone, tagging and releasing most to benefit the National Marine Fisheries Service's Cooperative Shark Tagging Program.
