A Shark's Deadly Equipment

Over the past 400 million years, sharks have evolved into nature's perfect predators. They can attack silently and with great bursts of speed. Their jaws can snap a sea lion in half, and their enormous gullet can swallow both pieces whole.

If limb-crunching, man-eating sharks haunt your nightmares, you won't enjoy knowing that there are nearly 400 species, ranging from about six inches to 50 feet long (15cm to 15m), inhabiting every oceanic corner of the globe. The good news is that most of them don't have the least interest in you.
