WONDERFUL CREATURES
SECRET SHELTERS IN
THE SEAS: CORALS
You may think at first sight that a coral reef is
merely a heap of colorful stones. Yet
you would be mistaken because corals
are living creatures. Billions of corals
live together, attach themselves
to others with special secretions
and bring this stone-like struc-
ture into existence.
