From scary movies to beachside signs, sharks have a hair-raising reputation. But are they really as scary as they’re portrayed?
The truth is, only 25 species (out of 368 species) attack humans, and only about 100 people each year are attacked by sharks. More people die every year from bee stings, natural disasters such as earthquakes, hurricanes or lightning strikes, volcanoes, and tens of thousands die in car and road accidents. The bull shark is the shark most often responsible for attacks, because it swims in the same shallow waters preferred by swimmers.
Sharks are ancient animals. They’ve been on earth for at least 420 million years. Sharks, unlike most fish, don’t have bones, but cartilage, which is a soft, sinewy substance. They have several rows of teeth and might have as many as 3,000 teeth in their mouths at one time. When one tooth falls out, another one moves forward to replace it.
