Advertisement I visited the Pittsburgh Zoo and PPG Aquarium yesterday. I was a little disappointed to see the employees standing outside with tarantulas in their hands in the rain while children came up to pet them. The one female employee said, "It keeps trying to run away!" No kidding. I was also surprised to see all the tarantulas set up on some type of wood chip substrate with no open water to drink from. They all had sponges custom fit to the exact size of the water bowls. Sigh.
