I have had quite a bit of interaction with crocs, alligators and caiman. A lot of it is related to snake collecting in the swamps but possibly the most interesting in crossing a then unexplored jungle, http://www.image-ination.com/Darien/.
I have always been fascinated by them. As a youth I kept five Caiman and a alligator in a pond in the back yard. The alligator grew faster than the caiman and eventually ate them all. One day when I was away at college it bit my father and later died in a mysterious accident.
What may be of interest is it easy to call alligators. Hold your mouth open. Press your tongue against the roof of your mouth and emit sort of a "gung" sound with a click sound. Do this repeatedly. The alligators will usually come streaming. The males looking for dinner as the sound mimics the sound of baby alligators. I assume that the females are coming to interrupt dinner. I have tried this with crocodiles without success.
