Crocks down south?
Here's a subject for discussion...

In recent years persistent rumors keep appearing about saltwater crocks reappearing in some of the Pilbara creeks rivers where they were last shot out back in the late 50's and early 60's according to the locals!

We know saltwater crocks were in the Pilbara waters that far back, and I guess with them not now being hunted in the Kimberley they are breeding up to the point where - they will eventually spread south and re-populate area's like the Pilbara where they once thrived...

So - the question that bugs me - is this!

If the warm water currents etc are headed south with global warming, and we have been seeing things like Mud crabs down in Augusta, and Bunbury etc...and Spanish Mackerel in Flinders bay at Augusta, Giant (wolf) Herring at Augusta and even Walpole...etc...

Is there any fear that crocks might find their way south like these other tropical species and if so - should we be keeping an eye out for when they do eventually inevitably arrive?

I mean we have mangroves now as far south as places like Shark Bay, The Abrolhos and even near the Parade Hotel in Bunbury!

So is there any physical reason why there CAN'T be crocks down south?

Discuss!
