Dear MEL School’s Topic Readers,
Emperor Penguins get too
hot
Penguins can swim but can’t
fly. More importantly, they can keep themselves warm enough to survive in Antarctica
where temperatures goes -20°C or below in winter, cold enough to keep tuna meat
vividly red, suitable for sashimi. As you most probably know, they gather closely
together to form a huddle to stay warm in the severe winter. You can easily imagine
that penguins on the outskirts must endure icy winds and feel the coldest. But there
is something else going on inside the huddle.
Researchers have recently
found that the ones on the inside the huddle get too hot, for penguins, so that
penguins in a huddle constantly change their positions to get wormed and
cooled.
Enjoy reading and
thinking what the life for the flightless birds is like on the coldest continent.
