Video shows an Australian Lung Fish, Stingray, Hammerhead Shark, Sharks, Poison Arrow Frog, Boa constrictor, and a Monitor Lizard. Few films of the Australian lungfish exist. It is listed as endangered.
What other fish are shown here? The display is gone and can't find out the names of the rest?
The Australian/Queensland lung fish/lungfish (Neoceratodus forsteri) is a unique living fossil. It is the sole member of the family Ceratodontidae and one of only 6 lungfish species that exist.
Note how the faces of the lung fish resemble those of some amphibians. Also note how their fins are under their bodies as are the limbs of land animals and how they use these fins to "walk" underwater.
It normally uses its gills for breathing, but can also take in oxygen from the air.
The species belongs to an extremely ancient group, called the fleshy-finned fish that are over 400 million years old. Fossils of identical fish have been dated at over 100 million years. Thus, it is one of the very oldest surviving vertebrate species. Lungfish are not now considered the direct ancestors of Amphibians, but resemble a common ancestor. All vertebrates including ourselves are descended from this ancestor.
This is the most primitive type of lungfish - compare it to the African lungfish.
A sting ray/stingray killed world-famous "Crocodile Hunter," Steve Irwin on September 4. 2006. Although docile, they attack when they think they are in danger. This was a freak accident. Stingray venom is extraordinarily painful, but not normally deadly. However, in Irwin's case the barb pierced his heart.
