Off the Menu
One of the world's most ancient species, the shark has had many years in which to decide upon a staple diet. Yet we so often assume that they would like nothing more than to make a meal of a human. In fact, experts in shark conservation have found that although the shark's diet is comprised of meat - often in the form of turtles, fish and seals - humans are off the menu. Due to the slower nature of their digestive system, sharks prefer to hunt creatures with fewer bones and higher levels of fat. A meal containing more fat, such as a seal or a sea lion, will give the shark a prolonged source of energy.
Mistaken Identity
Sharks are renowned for being very inquisitive creatures; on seeing objects that they are not familiar with they will almost always investigate. However, as they are ill-equipped to feel the object they are investigating the way humans and other animals with paws can, they rely on their snouts and jaws to do the detective work. Unfortunately this is how so many shark attacks occur. However, in most cases, once sharks have realised that the unfamiliar object is not a morsel, they will release it immediately. With at least 90 per cent of shark attacks being a simple case of mistaken identity, it would seem the shark is a much misunderstood creature. What could be more rewarding than helping shark conservationists to overcome the bad reputation the shark has gained through its own curiosity?
Looks Can Be Deceiving
With a fully grown tiger shark reaching a length of between 10 and 14 feet, and weighing up to 700 kilograms, it is no surprise that many humans are afraid of them. Their size, along with the enormous number of teeth that they have, gives them a somewhat fearsome appearance. However, it is too easy to overlook the majesty of these animals. Adolescent tiger sharks are marked with dark, vertical stripes, from which they have gained their name. These stripes fade as the shark matures, but they remain a beautiful colour all over. Though they may look initially intimidating, spend some time watching them propel themselves through the shallows and you will begin to see what those interested in shark conservation see; fear will give way to wonder as you are won over by their grace and elegance.
Understanding the behaviour and movements of the tiger shark is important to their survival. Taking part in a shark conservation programme not only gives you the chance to contribute to their protection, but also affords you the opportunity to explore and dive some of the most fabulous coast line in South Africa, to swim with sharks with no cages between you, and finally, to lay all your fears of sharks firmly to rest.
