| Piranha Fish |
In South American rivers swims one of
the world’s most dangerous fish—the piranha.
This savage fish is only ten or so inches long, but its teeth are so
sharp and its jaws are so strong.
It can chop a piece of flesh from an animal
or a human as neatly as a razor. Piranhas often travel in schools of several
hundred.
Their diet usually consists of other
fish. But if an animal happens to be in
the water near a school of hungry piranhas, they attack and devour it
instantly. Animals as bit as a horse
have been eaten down to a bare skeleton in only a few minutes. – Dick Rogers

| Corals |
Beneath the surface of the sea lie coral
formations of many shapes and colors.
The formations may look like branching trees tinted green or lavender,
lacy sea fans, or even like tiny organ pipes.
Coral is formed by millions of tiny sea animals called “coral
polyps.” Coral polyps look much like
little flowers.
They wave food into their mouths with
a circle of tiny tentacles. Young coral
polyps attach themselves to older ones and build limy, cup-like skeletons
around their soft bodies. When the
polyps die, their hard skeletons remain as part of the growing coral
formations. – Dick Rogers
