 Sea turtles nest on the shores or Pinellas' barrier islands and have been threatened by development.Offshore, dolphins, sharks, and manatees are numerous as well, while closer inshore stingrays are a common sight, leading those in-the-know to do the "stingray shuffle" (shuffling up the sand to scare nearby stingrays off) when entering gulf waters.Species of fish commonly caught in the waters surrounding the county include spotted seatrout, red drum or redfish, snook, pompano, sheepshead, Spanish mackerel, grouper, mullet, flounder, kingfish, and tarpon.
