How does the poison arrow frog communicate to animals that are color blind that it is indeed poisonness?

Presumably it fails to communicate its unpleasantness to every conceivable predator.

This is a common anti-evolution argument that goes as follows, "Since adaption 'x' does not work in every situation faced by species 'y' evolution is a crock...". The argument misses the point that the benefit of the adaption is still apparent in other situations, and as long as the cost of the adaption is less than its overall probabilistic benefit natural selection will tend to preserve it. Nature doesn't insist on perfection, most of the time good-enough is good-enough.

Not arguing evolution here.

Arguing perceptions.

I don't dispute that some mechanism made life on this planet more complex.
