Perhaps no other ocean creature lives in the human imagination like the great white shark. But while great white sharks might be plentiful in the minds of beachgoers across the country, there are only a handful of places in the world where white sharks can be consistently found. In those areas -- such as Central California, Guadalupe Island Mexico, South Australia and South Africa -- they tend to be found aggregated in small hotspots, often located around seal colonies. Researchers have estimated that white shark populations are incredibly small, with only hundreds of large adults and a few thousand white sharks total in any of their global populations. This has made protecting white sharks a priority for conservation with many countries, including the United States and Mexico, having laws in place to prevent the catching and killing of the species.

Processing over 3, underwater videos of great white sharks taken during a five-year population study is laborious work. It can entail frame-by-frame inspection of video collected on over trips off Cape beaches, looking for color patterns, scars, frayed fins and other physical features that are unique to each individual shark. The field work for the population study — tagging over white sharks and videotaping them to look for identifying marks — finished in But the unexpected retirement of one of the critical team members set back completion of the video identification process and delayed a much-anticipated population estimate of sharks that come to the Cape each spring through fall to feed on seals.
Ask any shark biologist a question about sharks, and chances are, the answer will begin with, "We're not really sure, but…". That's because researchers know remarkably little about these deep-ocean creatures. There are more than species of shark, and many of them fare poorly in captivity, making it difficult to observe their mating, navigational, learning and social or anti-social behavior. In celebration of the Discovery Channel's "Shark Week," here are seven mysteries that scientists have yet to solve about sharks. The open ocean has few visual cues, so how do sharks know where they're going?
