A
How Do Animals Catch Their ZZZ’s?
Different creatures have
developed some pretty creative ways to get their rest and stay safe.The lizard（蜥蜴）likes to sleep at the far end of
small branches hanging out over a pond or lake in the rain forest.If a snake
tries to slither up the branch to eat it ,it will shake the branch and knock
the lizard off,and the lizard will fall safely into the water.Chameleons can
change color to match their surroundings in order to hide even while sleeping.
Gorillas（大猩猩）like to sleep high in the
trees.They build a new bed every night,sometimes taking up to half an hour to
pile branches ,twigs ,and leaves into a comfortable bed .Birds also find it
safe to sleep in the trees,but unless they have eggs or young chicks ,they don’t
use a nest .They just lock their feet around a branch and hang on .A special
tendon（腱）in their
legs in automatically tight when they are at rest ,so they won’t let go and
fall.
Dolphins live underwater,
but must come to the surface to breather .Scientists now believe that dolphins
may sleep with only half their brain,while the other half stays awake to keep
them safe and breathing.Seals also do this,lying on their sides on the
surface of the water with one flipper underwater paddling to keep their noses
above the surface.Some ducks may also have this ability,and actually sleep
with one eye closed and one eye open.
