Very interesting, Carolyn.
When I was in college I worked part time in a psychology lab and was involved in running an experiment teaching Goldfish to match the color of an item to another of the same color. Some of the fish did fairly well at it. This is why I am especially interested in hearing about science like this.

It must have been amazing to be involved in something like that!
