Here's an experiment I performed, you can try it if you care to. I just went to my preferred search engine and did an image search for "animal". I had to scroll down about thirty images to find something that wasn't a mammal. It was a lizard. Most of the animals were fuzzy. (I may have missed some marsupials, to be fair.) I believe these search results are reflective of what people are looking for when they search "animal," and it isn't fish. Are fish animals? I would agree. Is it normal to feel differently? I believe so.
