Death from the disease chytridiomycosis caused by the chytrid fungus.

The Sharp Snouted Day Frog (or Sharp-Nosed Torrent Frog) is a locally abundant species that can only be found in North Queensland. For more than 25 years now, there have been no confirmed sighting of this small, diurnal amphibian species prompting the Australian government to declare it, along with other two other frog species, as extinct in the wild.

The fast dwindling of the Sharp-Snouted Day Frog’s population is caused by an infectious fungal disease called Chytridiomycosis, which is also affecting amphibians from all over the world – even leading to 100 per cent mortality rate for some species.

Scientists tried to prevent the complete annihilation of its population by sending a number of tadpoles for captive breeding to selected local universities and zoos. This, however, proved to be unsuccessful as the remaining individuals died as well, which officials suspect is due to the same disease that wiped them out in their natural habitat.
