FOR five years students from Macquarie University have been visiting Jervis Bay to study Port Jackson sharks in an attempt to uncover the little-known habits and personalities of the species. 

Macquarie University biological sciences associate professor Culum Brown has been working with local marine biologists and students to track the animals’ movements with acoustic tags over a season. 

“We want to figure out what the Port Jackson sharks do with themselves when they arrive and then what they do when they disappear again,” Mr Brown said.

So far studies show the individual sharks return to the same reef year after year.

Jervis Bay was chosen as a prime spot to study the species of shark because they were found to accumulate in the area in abundance each winter period.
