One, sharks are not mindless predators nor sinister man-eaters, and two, the oceans are not full of sharks."- Jean-Michel Cousteau
For thousands of years, sharks have haunted the human imagination. These perfect predators, 400 million years in the making, are unique hunters with awesome power. But their reputation as cruel, senseless killers of human nightmares is a far cry from reality. These powerful creatures play a vital role in the intricate balance that makes up the oceans' ecosystem. Today, a new predator, the human, puts these amazing creatures at risk, giving sharks far more reason to fear us than we have to fear them.
Brutal modern fishing practices, such as long-lining, and new demand for shark fins have decimated shark populations around the globe. Every year, 100 million sharks are killed by people. (An estimated 50 percent of those deaths are accidental, sharks getting caught up in nets that are set to catch other kinds of fish.) In fact, the populations of great white and hammerhead sharks have plummeted by 75 percent over the last 25 years. But this slaughter has not drawn much public sympathy because many people view sharks as a menace. Yet the truth is that sharks are a vital link in the food chain. When shark populations decline sharply, the results can be dramatic, upsetting the balance of the oceans and producing unintended consequences with effects that can reach around the globe.
Sharks strike terror into the hearts of people around the world like no other creatures. Their fearsome appearance, large size, and hostile, alien environment combine to make them seem like something straight out of a nightmare. The sudden violence of a shark attack is truly a terrifying experience for the victim -- but are sharks really man-eating monsters with a taste for human flesh?
Although shark attacks can seem vicious and brutal, it's important to remember that sharks aren't evil creatures constantly on the lookout for humans to attack. They are animals obeying their instincts, like all other animals. As predators at the top of the ocean food chain, sharks are designed to hunt and eat large amounts of meat. A shark's diet consists of other sea creatures -- mainly fish, sea turtles, whales and sea lions and seals. Humans are not on the menu. In fact, humans don't provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies.
If sharks aren't interested in eating humans, why do they attack us? The first clue comes in the pattern that most shark attacks take. In the majority of recorded attacks, the shark bites the victim, hangs on for a few seconds (possibly dragging the victim through the water or under the surface), and then lets go. It is very rare for a shark to make repeated attacks and actually feed on a human victim. The shark is simply mistaking a human for something it usually eats. Once the shark gets a taste, it realizes that this isn't its usual food, and it lets go.
The shark's confusion is easier to understand once we start to look at things from the shark's point of view. Many attack victims are surfers or people riding boogie boards. A shark swimming below sees a roughly oval shape with arms and legs dangling off, paddling along. This bears a close resemblance to a sea lion (the main prey of great white sharks) or a sea turtle (a common food for tiger sharks).
Attacks have also frequently occurred when humans were spear fishing in ocean waters. Sharks are attracted to the signs given off by dying fish -- the smell of blood in the water and the electrical impulses given off as the fish struggles. Sharks detect these signals with their ampullae of Lorenzini, a set of "detectors" under the skin on a shark's snout. The ampullae are electrically sensitive cells that connect to the skin's surface through small tubes. Once a shark arrives on the scene, it may become agitated and aggressive in the presence of so much food. A hungry, excited shark can easily mistake a human for its usual prey.
There are cases in which sharks seem to attack out of aggression, rather than hunger. Very little is known about shark behavior, but it is believed that some species, including great whites, display dominance behavior over other sharks. This behavior can take the form of "punching" with the snout, or bites that don't do much damage to the tough skin of a shark. Unfortunately, when a shark makes a dominance display toward a human, these "gentle" bites can still cause horrendous damage.
Sometimes, the cause of a shark attack is simple to determine -- the shark is responding to human aggression. Nurse sharks, for example, are generally placid fish that lie still along the bottom of the ocean floor. For some reason, this makes some divers think that it's a good idea to pull their tails. Irritated nurse sharks have taught several divers to keep their hands to themselves. For this reason, shark attack statistics are divided between provoked and unprovoked attacks.
It is impossible to say that there are absolutely no rogue sharks -- individual sharks may exhibit strange behaviors, possibly because they are sick or injured. Differing ocean conditions can send sharks beyond their typical range as they follow their prey species.
However, there is no evidence to indicate that sharks ever "develop a taste for human flesh." Even if there is a series of attacks in one area, sharks tend to travel great distances in one day. That means the shark that made the first attack is probably hundreds of miles away when the second attack occurs. Scouring the area with fishing boats and killing sharks hours after an attack is unlikely to bring in the specific shark that attacked.
There is rarely any warning. The surfer or swimmer is paddling along with no idea what is about to happen. Sometimes their first indication that something is wrong is a look of terror in the eyes of a nearby friend. More often, the first sign is a sudden, massive impact as the oncoming shark propels itself into the victim. Great whites are known to attack sea lions with such force that they leap completely out of the water with the prey held in their jaws. In the book "Shark Attacks," pregnant lifeguard Dawn Schaumann recounts her attack, which happened about 100 yards off the coast of Florida in 1993: "A shark hit me so hard it felt like a huge truck," she said. "My first thought was: my time has come."
Surfer Kenny Doudt was attacked by a great white shark off the coast of Oregon in 1979. He describes the attack in his book, "Surfing With the Great White Shark": "I heard a muffled roar as the shark's massive jaws clamped across my back, pressing the board to my chest...The shark pulled me two feet under water, but couldn't hold me under due to the buoyancy of the surfboard...I felt tremendous pressure on my chest and heard ribs snapping and the crunching of the underside of the board."
The attack started out as if the shark was feeding normally -- great whites attack sea lions from below, taking a single massive bite and dragging the prey below the surface. They then allow the disabled prey to float in the water and bleed to death, returning to finish their meal a few minutes later. In Doudt's case, the shark was unable to accomplish its initial bite because of the surfboard, but kept trying for about 20 seconds. "I felt totally helpless, as my entire body was lifted high above the water, then slammed back down beneath the surface," he recalls.
Eventually the shark let go of Doudt and he never saw it again. Although he feared a subsequent attack as he paddled for the shore, the shark swam off and did not make a second strike. The shark probably realized that a surfer and surfboard would not make a good meal. Great whites are actually very picky about what they eat -- refusing to bite things that were not their usual prey, such as floating sheep carcasses, after an initial taste.
However, there are many species of sharks, and not every shark follows the same pattern. Circumstances can also change the pattern of attack. Shark attacks in deep sea water are usually not hit-and-run attacks. In these cases, where the victims are often the survivors of sinking ships or plane crashes, sharks circle the scene. They will then bump into victims on the outskirts of the group, or those that are already wounded, before making bite attacks.
One of the most famous shark attacks is that of the USS Indianapolis, sunk by Japanese torpedoes in the Pacific Ocean in 1945. It took several days for rescuers to reach the ship, because the mission had been so top secret that no one reported the ship missing. By the time Navy rescue craft arrived, only 317 men were still alive out of the almost 1,000 that survived the initial sinking. Tiger sharks were responsible for most of the deaths. 041b061a72
