Andrea Queen of Mantas BBC 2009 Natural World

Manta rays are one of the most intelligent creatures in the ocean and, at up to seven metres long, one of the largest. Yet despite their size and curious nature, almost nothing is known about their lives. Young marine biologist Andrea Marshall has given up everything for a life in Mozambique, diving amongst these beautiful animals. Superb underwater photography reveals new manta ray behaviour including breathtaking footage of their ritual courtship dances. The film follows Andrea as she studies these endangered animals up close. With the discovery of a giant new species and remarkable insights into mantas' secretive lives, Andrea's findings are already rocking the world of marine biology.

I’d heard a lot about the Whaleshark population in Tofo from friends and divers making their way around Africa. By all accounts there was a large population of these giant filter feeders and it was fairly common to see several Whalesharks in the same area. Our job though was to film the other population of massive plankton scoopers, the manta rays. Dr Andrea Marshall has been studying the population in Tofo since 2003 and The Manta Queen was focussed on her efforts and her remarkable discovery which has focussed attention recently on this small, remote location. The manta ray (Manta birostris) population around Tofo Beach is the largest currently known in the world. During her studies on the Manta population of Tofo Andrea noticed that, while their seemed to be a resident population of Manta rays, there also seemed to be some larger and more transient Mantas which arrived on dive sites such as Manta reef off Tofo then disappeared a few days later. Peaking her curiosity, Andrea’s further studies revealed a genetic difference. Now where once the scientific community thought we had one species of Manta we now have two and possibly even three! Myself and the rest of the Bigwave TV production crew spent a productive and fun ten days in Casa Barry, Tofo filming some great sequences of Andrea and her research partner Simon Pierce as they attempted to tag Manta rays with acoustic and satellite tags in order to monitor their movements. We also had a chance to get in with the whale sharks and grab some pics of visiting scientist Rachel Graham as she deployed tags on the sharks. On a sadder note we encountered a manta ray caught inadvertently by fishermen a few miles from Tofo. Dr Marshall took the opportunity to take something positive from this unfortunate event by taking measurements and samples from the ray.)
