3.4 Is it possible to tame a caiman or other crocodilian?

In theory yes, it is possible to tame a crocodilian. However, it is exceedingly difficult, and most animals will only become moderately calm at best. Many people have tried to tame their animal, with limited success. The only crocodilians that I’ve seen which would be described as "tame" had been handled every single day of their lives for extended periods of time. Even then, the animal is still capable of inflicting a serious bite, and the feeding reflex of a crocodile can be very difficult to inhibit. Individual temperament varies a lot between animals, and some are certainly calmer than others. Some species also tend to be more docile than others, but all are capable of giving you a nasty bite when they’re in no mood to be approached. Never buy any crocodilian on the pretence that you will be able to tame it - disappointment will probably be the most likely outcome, with only bite scars to remind you of your attempts.

The Number One Rule when dealing with any crocodilian is to never drop your guard and completely trust the animal. Always be aware of what it is capable of, and respect both its bite and its speed.
