The shark is the one on the left, not right. They are especially strong since those long things on their noses are barbels.
DJ is right. The one on the left goes by the scientific name
Pristiophorus cirratus and is found in the waters around southern Australia’s outer continental shelf, and is endemic to that region.
There are a few different varieties of saw shark, but they all come from the Pristiophorus family. Lay people will often refer to a sawshark as a sawfish though, so it's possible that's where the confusion arises? You can see that the one on the left has the two longer prongs. That's what identifies it as a saw shark. The one on the right doesn't have them and the structure of the snout is different.
