Baby Einstein dvd's content, are some animals inherently frightening or is that just my impression?

I'm curious here: the Baby Einstein DVD's have animals and stuff in them, someone gave me one about oceans and another about animals in general. To those parents who have watched Baby Einstein do they show frightening creatures like sharks, spiders, and crocodiles? Or are those considered scary for a baby or toddler? I'm afraid to watch the ocean one, for example, because Im terrified of sharks, are they scary for babies or is that just my impression because of my fear?
