Geckos
Most North Americans are familiar with geckos, but not many have actually seen one. Here in Brazil they are very common. We usually see them in the evening on the exterior walls of the house, but we have seen them in some strange places -- like stuck in the light fixture in Kilah's bathroom. Geckos are a welcome sight here as they help keep down the mosquito population, which isn't terrible in the city, but it's bad enough. They are about as harmless as a creature can get. Their only defense mechanisms are to run (which they do quite well) and if necessary, shed their tail if being held by the tail. After the tail comes off it keeps moving -- very interesting to say the least!
