Acoustic-tracking studies at NMP have revealed that individual whale sharks sometimes stay close to Ningaloo Reef over day/night periods. In addition, using the ECOCEAN Whale Shark Photo-identification Library, it has been possible to record many sharks returning to Ningaloo in different years and staying there over long periods. As an example, one individual was sighted at Ningaloo Marine Park on 14 separate days over a 28-day period within a small area.
Are they migratory?
Whale sharks are highly migratory, but little is known about their migration patterns. Research at NMP has shown that at least some sharks take a northerly route when leaving the area. Satellite tracking has shown that they can travel great distances.
