This explains the abundance of fossil shark teeth. The Great White Shark appears to be a finicky eater with little taste for humans. In 78 attacks recorded along the California coast since 1926, there have been just 8 deaths. Most surfers they just spit out. There are almost six billion people on our planet, and less than 10 are killed by sharks each year.

The longest gestation period for any animal is that of the spiny dogfish, 22-24 months. In the United States, the annual risk of death by lightning is 30 times greater than that of shark attack. Bites or stings from bees, wasps and snakes cause more deaths per year by far than shark attacks. Of more than 350 shark species, less than 10 are considered dangerous to humans. The largest ocean dweller, the Blue Whale at lengths of about 90 feet, is a mammal.
