|[Note Guidelines] Photographer's Note|
|They are a tropical rays, related to sharks,|
and are found in Australian estuaries (ie river mouths where the saltwater mixes with fresh) and freshwater rivers/creeks.
They have a flattened body with a prominent long flat "toothy" snout
Hence they are sometimes referred to as "Sharks with Swords"
Its shark-like tail propels it through the water with graceful undulations, and the flattened body and head indicates a bottom dwelling fish.
The sharp awl-like teeth are not true teeth at all; they are really modified scales, but the jaws are lined with a pavement of thousands of tiny As with other rays, the mouth, Nares (nostrils), & gill slits are located on the flat undersurface.
Colour wise they differ depending on species and location but the upper surface is dark to blend in with the muddy seafloor; the underside is white, to blend in with the water surface when seen from below.
Females give birth to live young which have a "soft" saw.
Sawfishes eat only small fish and bottom-dwelling invertebrates, like crabs and shrimps, which can be crushed and swallowed whole through the mouth.
These flattened shark-like rays, born about 0.65m reach lengths of over 6.6m!
The freshwater species is Australia's largest freshwater fish.

Amazing looking fish, Amos.
The details are very sharp.
Really nice presentation of the "saw".
What is that fish doing out of water lying on the sand?
TFS. : )
Welcome to TrekNature and I hope you will enjoy this site as much as I do!!
I was stunned, when I saw the title of this photo and the location - but now I saw your answer to manyee - et voila, now I know.
VERY GOOD photo. It is always difficult to photograph in an aquarium due to the reflection of the glass and the underwater spotlights! I see you did not use the flash - did not fire - therefore no reflection on the glass.
The natural colours are a bonus.
Have a nice week,
Greetings from South Africa
