Death from the disease chytridiomycosis caused by the chytrid fungus
The Armoured Frog prefers to stay in fast-flowing streams and creeks in Queensland where it can only be found. This critically endangered species on the IUCN Red List has a grey-coloured back and a white-coloured belly, growing up to 37 mm (1.5 in) in length only. Males have distinct spines on their thumbs and chests, believed to provide a better grip during mating period.
There is no verifiable reason for the population decline of the Armoured Frog but the disease caused by chytrid fungus is suspected to be the top culprit, something that has caused high mortality rates among many amphibian species around the world.
In 2011, however, Dr. Robert Puschendorf confirmed a group of fungus-ridden Armoured Frogs has been thriving in the same Australian rainforest but in an area where it is drier and receives less rainfall. He and his colleagues believe that these conditions either helped these frogs cope with the disease just fine or just slowed down the effects of the fungus infection.
