Chris, first you agree with me but then you say that they would not
respond to anything less than a hippo. So which is it? Also, I would
imagine that during the "act of killing" a croc would not respond to much
of anything, it has already committed itself, and is going to hold on no
matter what. Pit bull terriers do the same thing. But that is different
than responding to a threat display, don't you see? The fact is, I think
I could drive off a croc with a stick and some big rocks. I probably
could do the same to a lion, but to tell you the truth I would feel more
comfortable doing it to a croc.

Well, whether or not a land based mammal could make a living there was
not the point of the post. I was simply pointing out that there are
places where crocs don't live, and you essentially agreed with me by
saying "crocs may not frequent such environments"

Well, the reference said "Salt water crocodile is actually a mis-nomer".
Whether you agree with that or not is up to you, but I know how much jim
prefers the "power" of a good reference ;) But it makes me wonder why he
doesn't reference Elaine Morgan very often ;)

Well, this guy actually posted names of lakes in eastern Africa where
there were no crocodiles.

So let me get this straight. You are saying there are no aquatic
environment in Africa that are free from the crocodilian menace?
