Bob's gotten bigger since the last time I saw her! (the gator without a tail is a female named 'Bob') Your daughter is adorable. My daughter was about the same age years ago when we took her there. Thanks for the tour!
Bull alligators can get up to about 13 feet long. The largest crocodile in captivity is just over 18 feet long. (Cassius at Marineland Melanesia in Green Island, Australia). Many massive crocs get to around 16 feet though, depending on the species.
