` They're individuals, some individuals, and some strains, are very calm and not aggressive. Others can be terrors. Who their parents are, and how they react to the first few months of life, are the two determining factors. Like any other snake it is the nature of babies to be nervous, and worse. If you push babies, even a little, they fall back on instinct, and become defensive or offensive.
` Six years ago, I found a strain that produces very calm, and non aggressive critters. I immediately bought several babies. Now, as young adults, they are quite tame. They go to elementary schools, and do presentations. They're handled by dozens of kids. Never been a problem. The nice thing is that their behavior is quite consistent. I also have a huge female Yellow who will not allow you to disrespect her, and she doesn't bite either. Having a 13 + foot, 60 some pound Anaconda strike at you, even though she doesn't open her mouth, makes an impression. She will also slap you with a coil, and has left some nice bruises.
` The thing is, Anacondas, even Yellows, get large, and are strong. You've got to know the snake you're dealing with. If you get them as neonates, you have plenty of time to learn what to expect from that snake, as far as general behavior, before it gets large enough to be dangerous. You've just got to remember what my friend says: "When one of my Corns, or Milks has a bad day, nobody dies."
` Here are some pix of the general temperament and behavior of this group of Yellow Anacondas.
