People from around Fiji will spend the next month counting shark sightings, as part of a census of the country's species.
The Great Fiji Shark count is in its second year, as part of efforts to find out the shark popoulation, and how it is trending.
One of the coordinators, Manise Ledua, says there are 25 participating dive companies and resorts across the country.
"So hopefully, they will give us the correct data, and not just something they've made up, because this is scientific, so we really need exact [data], and the co-operation of these people, so that we will know the trend of the shark population in Fiji."
Manise Ledua says people will also be counting rays and turtles.
