Silent Predators

Did not go for my walk, the kids are caught up in Smackdown! vs. Raw and I got caught up in the movie mentioned in the title. I love Sci Fi.

The movie, Silent Predators, is about hybrid rattlesnakes. That seem to only attack humans. One of the snakes made the choice between attacking a dog which was closer and barking at it and a little girl.

Why are there so many science fiction movies about snakes?
