To a point routine works don't get me wrong and getting the croc in a crate is different than swimming with it like that guy was. They have to have some intelligence they've survived longer than most species, but I don't think they have emotional intelligence. I can say come here stupid to my dog and he comes because he wants me to pet and snuggle him. I say sit and he does because he wants to please me, but I don't think a croc would respond to the human out of love/loyalty and more routine and reward. It's interesting data but I still think while all animals can be trained to a point there is a huge difference between those with emotional intelligence and those who are reponding to the routine of the reward system. What is motivating now may not be motivating in the future because for the croc the response is not connected to a feeling of love, loyalty, and accomplishment and rather just a signal to act if they want the reward and when they no longer care about the reward someone's becoming lunch
