(CNN) - A unique species of crocodile lives in New Guinea, but in 1989, a researcher suspected that there may be more to the story on the tropical island. But the large island north of Australia is divided by a mountain range, creating distinct habitats in the north and south. They attended a talk that raised Hall's research and asked for help to finish the investigation distinguishing between the New Guinea crocodiles. "Our work adds to this with additional morphological insight into how distinctive these two species of crocodiles." The crocodile species in the south has now been declared a separate species and the researchers named it Crocodylus halli in honor of Philip Hall.
