The ones I'm talking about are the Short-finned Eels, Anguilla australis (yes, I had to look up the scientific name!). By far, most of the freshwater eels I've seen around Victoria have been this species, although you're right, the Long-finned Eel also occurs in the area. The Long-finned Eels are more of a river thing, so probably wouldn't be as well adapted to surviving the nasty dry conditions, although I've had little to do with them.

That these things manage (as tiny babies!) to cross so much land to get into isolated bodies of water, then grow into great big eels and slither back into rivers and out into the ocean still astounds me.
The Long-finned Eel, Anguilla reinhardtii is fairly similar and their ranges overlap. Both do the same 'swim out to the ocean, breed, die and let the babies swim back to fresh water' reproduction.

I thought long-finned eels were the common ones.
It is amazing some of the places they are found, we swim with them regularly at a place that has at leat 50 rapids to navigate before they get there.
