A flightless aquatic bird.
In the wild they are restricted to the southern hemisphere, with many nesting on Antartica, where there are no land-based preditors so their flightlessness is not a disadvantage.
LinusTorvalds is from Finland, and I believe penguins are native there. Linus actually got a penguin for Christmas in 1996, which is kept in his honour at the Bristol Zoo. See
