Koala \Ko*a"la\, n.
   A tailless furry marsupial ({Phascolarctos cinereus}), found
   in Australia. The female carries her young on the back of her
   neck. Called also {Australian bear}, {koala bear}, {native
   bear}, and {native sloth}. The koala lives almost all of its
   life in trees, moves sluggishly like a sloth, and eats
   eucalyptus leaves almost exclusively.
