Great White Sharks

A new investigation into shark populations in the waters off Australia has discovered that there are two distinct species of great white shark, one to the east and one to the west of Bass Strait. This was discovered by tagging large numbers of sharks in the coastal waters all round Australia. Rather to the investigator's surprise, they found that while sharks from the east side certainly travelled to the west side of the continent and vice versa, they always returned to their home areas to breed. The two types of shark were found to have a distinct genetic make-up indicating that interbreeding has not taken place. The implication of these research findings is that sharks may be more susceptible to changes in local marine environments than had previously been thought.
