The competition to Windows and Mac OS, Linux also has a penguin as its logo (and mascot). Named 'Tux', the penguin was chosen from a list of sharks, foxes, eagles and hawks as the Linus Torvalds, the founder of Linux, had a liking for the bird and thought it to be unusual and different for a logo. While the other creatures were fierce and strong, Linus insisted on the penguin being “fat, cute and cuddly - instead of anything else. Incidentally the name 'Tux' was brought up from Torvalds UniX -TUX.
