We're stuck with fuzzy numbers again. Lots of animals
were wiped out from lots of place and if they weren't
wiped out from Africa it may be because many predators
weren't wiped out in Africa either.

in any case, the reinfestation is harder than for land
predators. It's too plain to argue about. Obviously
they can infest waterways that are close to one another or
connected. How the hell would they infest a river or a waterhole
20 miles away. I can't imagine a croc going for a 20 mile
walk and surviving it.

Make it 20. Make it 10. What's the big deal, when I'm
pointing out the difficulty of it all.

Sea warfare is not like land warfare. YOu can't "hold"
the sea like land; you have to search and destroy.

And crocs going over land is like land predators going over
sea lanes. Reverse the picture. Do you deny that it would
be more difficult?

How much distance?
