tux, a goofy looking penguin, is the linux mascot. usually different distros of linux have their own modified picture of tux.
1. A small, fat, flightless bird, commonly known to live in the Antarctic.
2. The mascot of all Linux Distros. Also known as Tux. This was chosen mascot, because while on a trip to a zoo, Linus Torvalds was bitten by a penguin, and he then attributed this to how Linux behaves at times, and hence, it stuck.
