Figure it out, I already forgot

I must give you a warning, this might get pretty deep. I look down upon any form of piracy. my favorite book is the Old Man and the Sea. My rival is as big as a whale. Anyone that sees my arms calls out "Sucker!" My friends may seem a bit fishy. I'm told I have an inflated head. I hate how the ink prices are rising. Occasionally I like lounging on the beach and people crowd around me. I have a part time job as a lab rat. I'm very camera shy. I prefer for it to be dark.
