You may not have said literally "walking catfish don't exist" but you

=============
As Johnson notes, the story to be tested is that a fish
species developed the ability to climb out of the water
and move on land. But here are the problems NO ONE has been
able to solve, to this day. Taylor at 56ff. (no ellipses!):
"The real obstacles to such a move were the massive structural
changes needed to make life on land worthwhile. To bein with,
the fish would need legs simply in order to relieve the
pressure of its body on the ground, which would compress the
lungs.
==============
You've been given two examples of fish that climb out of the water
and walk on land. The claims above are obviously false, do you want
to retract them?
