Sharks - How Dangerous Are They?

by Trevor Sinclair

Due to hollywood movies about sharks many people think of them as predatory creatures that will hunt down humans due to be blood thirsty. On the contrary sharks, don't even like eating humans. The blood of humans doesn't taste the same as the food they actually eat which is why when a person is attacked it usually just one bite.

The hunter's diet is comprised of fish, seals, and other assorted sea creatures. We find them so terrifying in part because of the characteristics they've evolved to fit into their ecological niche: strength, agility, and an enormous number of teeth.

Frequently, what happens is that humans cause the sharks to attack by inadvertently copying natural animal activity. They swim way out in the ocean, paddling on their surf boards as they attempt to ride the crest of a great big wave. They don't realize that they seem just like injured seals to the sharks swimming nearby. The result is a very regrettable accident, like a swimmer getting sucked up in a fierce undertow. The people shouldn't be doing what they're doing where they're doing it.

Despite this, on a very low number of people out of the millions who spend time at the beach each year get killed by sharks. Also, there are fewer shark attacks each year than you might expect and of the 90 or so that do occur, most only result in minor bumps and grazes. Whilst it is tragic that anyone should get killed by a shark, incidents involving sharks can be considered accidents rather than malicious attacks.

Strange though it may seem, falling coconuts actually cause 10 times as many injuries to humans as sharks do. The Tiger shark and the great white shark may be the most aggressive of sharks but they very rarely attack humans. You'll find yourself more at risk whilst you drive to the beach, bearing in mind that driving kills more than 40,000 people on the US each year.

It is only human to feel compassion for anyone who suffers a shark bite. However, one should also feel a similar sort of distress on behalf of all those sharks that will be slaughtered for vengeance. These creatures cannot comprehend the reason they are being tracked and murdered. Only humans can recognize the concept of punishment. Unless we eradicate them all, we are going to have to learn to live alongside them. We have certainly not achieved safety by attempting the former approach.

Although the Hollywood image of sharks has left many people afraid of the water, it is important to be aware of the fact that these fish are not seeking out humans as prey. In fact, shark attacks on humans usually only result in a single bite and they would prefer to eat their typical food rather than humans. Strange though it may seem, falling coconuts actually cause 10 times as many injuries to humans. The Tiger shark and the great white shark may be the most aggressive but they very rarely attack humans.
