Once again, sharks are in the spotlight as Shark Week promotes respect and appreciation for these remarkable animals (with excitement also part of the mix). … This year's new fare includes tonight's 'Surviving Sharks,' in which Les Stroud, host of Discovery's 'Survivorman,' offers tips for water safety and tests popular theories for surviving shark encounters."
