                                                          Both hamsters and gerbils are rodents, but they are different.  Hamsters are larger than gerbils while gerbils have a long tail versus the stubby hamster tail.  Hamsters also have large pouches in their mouths to carry food. In the wild, gerbils are desert animals who tend to be active during the day, while hamsters are active in the early evening.
