Who We Are Our People Scientists Frazer McGregor Frazer McGregor | Project Manta Ningaloo Reef PI Murdoch University Frazer has been a tour guide and skipper for 10 of his 15 years in Coral Bay, and has spent the last nine completing a PhD in marine ecology at Murdoch University. Frazer’s thesis has been instrumental in the implementation of the Manta Ray Identification catalogue. His research has collected data on almost 1100 different manta rays that visitors have the opportunity to interact with. His studies have provided key baseline information on all aspects of manta ray ecology within Ningaloo Reef including population ecology, foraging ecology and localized movements.
