Expedition leader Paul Rose, environmentalist Philippe Cousteau Jr, maritime archaeologist Dr
Lucy Blue, and marine biologist and oceanographer Tooni Mahto investigate how schools of
manta ray suffering from shark bites are treated by the inhabitants of a remarkable reef.
They go in search of one of the Indian Ocean's most elusive creatures, the dugong.
The expedition visits the only 'coral nursery' in this ocean, where an extraordinary
technique is being used to repair damaged reefs.
They investigate what is driving the increasing trade in shark fishing, and working with the
British Met Office, they take part in a global experiment to collect vital information about
the Indian Ocean.
