The Neoceratodus forsteri Australian Lungfish 39 is one of only six lungfish species in the world, and exists amongst stagnant or slow moving streams along the Burnett and Mary River systems in Queensland, Australia. It can grow to ~1.5 m in length and weigh ~40 kg, enjoying a diverse diet of plants, frogs, small fish and invertebrates. With the oldest known specimen reaching a ripe old age of 80, this ancient beast survives the rise and fall of stream levels using its fascinating ability to breathe in both water and air. They have gills like any other fish, and the Queensland Lungfish is the only lungfish with one instead of two lungs!
