The loss of sharks could contribute to the destruction of one of the planet’s most under-appreciated sources of carbon storage — seagrasses, according to...

Intense exploitation over millennia has depleted Mediterranean Sea species from the large to the small. What would a ‘healthy’ Mediterranean rocky bottom look like? There are no pristine sites (i.e. undisturbed by humans) left in the Mediterranean against which to compare the health of current ecosystems. SCUBA divers surveyed the rocky reefs throughout the Med, from Morocco to Turkey.

White tip reef shark

Shark fishing needs to be banned at Osprey and Shark Reef in the Coral Sea for a Marine Reserve to work, concludes a study published yesterday. It is estimated that each year, live-aboard dive boats are directly responsible for generating at least AU$16 M worth of income. Of all the Coral Sea reef systems, Osprey Reef has the highest visitation rate by tourism operators, primarily to conduct shark dives. So, the depletion of reef sharks at Osprey Reef would have serious financial ramifications for the area. To put this into perspective, in the Maldives, the removal of only 20 grey reef sharks, with a market value of only AU$1 000, caused an estimated loss of AU$500 000 annually in diving revenue.

Great white shark

Great white sharks may be among the longest-lived fishes. New study finds the shark can live over three times longer than previously estimated, which may mean it is even more vulnerable than thought.
