Sterling silver hammerhead shark charm. While the hammerhead shark may look a bit clumsy, they are the most agile of all sharks, and are highly specialized hunters. They can see in 360 degrees, twist & turn their bodies in a flash, and are equipped with specialized sensors to pick up tiny electrical pulses of all living creatures around them - even the beating of a human heart miles away. But, don't worry they have more to fear from us than we do of them. The next time you are feeling off track and need to find your way, channel the extra-sensory abilities of the hammerhead shark.
