Here is my one self-serving plug for a holiday gift item: Island of the Great White Shark on DVD.
Island of the Great White Shark was the first comprehensive documentary to examine the great white sharks of Isla Guadalupe and detail the working relationship between shark diving operators and dedicated Mexican marine researchers. You can experience what it's like cage diving with these magnificent sharks while also getting to see them in their real environment: critically important predators shown as they truly are and not the malevolent monsters of cinematic legend.
"A primal scene of unearthly beauty. Excitement and information pepper this film." - WetPixel.com
"Beautiful videography, good graphics and information." - Dr. Bob Hueter, Director, Mote Marine Center for Shark Research
Reasonably priced and available at Amazon.com or the gift shops of several leading aquariums, Island of the Great White Shark succeeds as a visually striking and informative overview of one of nature's most legendary creations, how it is being studied, and what threatens its future.
