The endangered Grey Nurse Shark has a series of pigmentation spots on either side of their body. These markings are unique to each shark (just as human fingerprints are unique to each one of us). A combination of relatively late maturity and low reproductive rates means that sharks are unable to replace depleted numbers. Shark populations around the world have dramatically decreased due to various human activities.
In Australia, seven shark species are listed as threatened, including the endangered Grey Nurse Shark. For over 70 years, shark nets have been protecting Australian swimmers from a death almost too awful to contemplate. Since their introduction in 1936, not one fatal shark attack has been recorded at beaches where nets have been installed. But a growing body of scientific evidence suggests that shark nets remove more than just feared predators from our beaches. Protected species such as whales, dolphins and manta rays also get trapped in these nets. Ironically, another protected species, the majestic but terrifying Great White Shark is regularly caught in shark nets insignificant numbers. No one really knows what removing such a high level predator from the marine foodchain will do.White sharks mostly inhabit coastal and continental shelf waters, from the shallow reaches of bays, islands and estuaries. They have been recorded over the continental slope to depths of at least 1280 metres.
Sightings, capture records, tagging and genetic data indicate that some white sharks also spend periods in the open ocean. Tagged white sharks have travelled up to nearly 10,000 km, over periods of liberty up to 10 years. Their residency at certain places tends to be interspersed with directed (and sometimes prolonged) periods of travelling, presumably in response to the availability of prey or reproductive cues.

Spot a Shark is a non-profit dive community research project that has been established in conjunction with the Marine Ecology Group at Macquarie University. We will be utilizing a computer based software program to identify individual sharks. Each grey nurse shark has a series of pigmentation spots on either side of their body. These markings are unique to each shark (just as human fingerprints are unique to each one of us).
