If you wanted a crocodilian which one would you go for? Alligator Caiman or Crocodile I personally would go with the alligator for 3 reasons: 1) Only the crocodile is more widespread 2) Alligators are more docile than caimans or crocodiles because they have been around humans for thousands of years and 3) If you start training as soon as the alligator hatches you can get the alligator to be nice towards people. If you then breed the tamest alligators, since there is a genetic component to that tameness the tame genes would pass on to the second generation of alligators and after years and years of doing that process they will have become domesticated. Wild alligators wouldn't even notice the difference but people sure would. The training would be sort of like this. 1) get you and the gator ready for it 2) say "Gator, come here" 3) give a reward to the alligator if he/she doesn't try to bite anyone At first the alligator wouldn't get it but after a few months it will start making the connections and after a year or more it will do it almost every time even without the reward. Zookeepers are using this process to train alligators and crocodiles to walk into the crates when they need checked so that they don't have to tape its snout shut and carry it into the crate. An 800 pound male alligator would take at least 4 people to carry it if not 8. This is risky since the people could accidentally cause the gator to get a dislocation without realizing it. The weight of the gator could also cause the zookeepers to get a dislocation. They could also get clawed by the gator and potentially bit. That is why they are training the alligators and crocodiles to walk into the crates is so that they can minimize the risk of injury.
