I think what you probably think is a throwaway remark about the almost extinct gharial is awful. We are the invasive species and we ought to be doing much, much more to save the animals that "get in our way". We destroy and pollute wherever we go. If we don't like something, because it's ugly (perceived to be) or it tramples our crops, we wipe it out. Look what has happened to the white rhino or the orang utan.It turns out that even scary crocogators love blowing bubbles. Don't worry, these guys only like fish. There's about 800 of these guys left in the world, so not much to worry about.
