An alien race I dreamed about the other night. They eat through their chest; they'll grab prey and hold it against their body, which is very sticky if they want it to be, and digest from the outside in. In the dream I was riding a train and one invited me to sit beside of him; he then tried to eat me but I slapped him away. I argued with him and told him 'It's rude to try and eat people on public transit' and he apologized lol...
