Do they migrate?
A tagging program was started in 2002 to understand the movements of grey nurse sharks along the east coast of Australia. Twenty-four sharks were tagged ranging in size from 1 metres to –2.61 metres Of these, 20 individuals had been resighted on at least one occasion within one year of tagging.
The research found that the same grey nurse sharks occupied particular sites along the coast at various times during the year. The sharks spent different amounts of time at particular sites. They traveled in one direction for distances up to 880 km and traveled from sites in Queensland to sites in central and southern New South Wales (and vice-versa).
Researchers are currently examining local grey nurse shark movements within the critical-habitat sites. The results of this work have shown that the sharks move out at least 1.2 km from their gathering site.
