Toads can't locate their food unless it is moving. One night I bounced
some small paper wads around this one toad. He only ate the ones that
were still bouncing when they went by his head. Then he'd spit
them out, but I didn't feel expanding my study to feeding. I guess
you could fish for amphibians this way. I wonder if most fish
are like this as well in terms of the type of bait they will
strike (stationary vs. moving)
