Scientists have found a genetically unique population of miniature sharks off the coast of Belize. The bonnetheads' DNA looked good - but it also looked sort of odd. The samples taken in Belize were startlingly different from the rest of the bunch.
Scientist Kevin Feldheim said he and his colleagues were quite surprised with their results. They thought they were doing a standard analysis of a shark population and suddenly they were looking at a whole new species.
