Shrimp Bucking the Crowd
by Eric Kreye
A small marine
animal
teaches a big lesson--it's the
lowly shrimp!
Every time it molts--and it does
this several times a year--this fascinating small creature does an amazing
stunt. It places a tiny piece of sand in its own head.
This grain
of sand is called a "statoscyst stone." Without it the shrimp has a difficult
time surviving its turbulent habitat because just a small tug of gravity helps
the shrimp to know if it is right side up or up side down. Because of the grain
of sand the shrimp maintains its equilibrium when tossed by the surging seas
during its molting stage.
A marine
biologist learned the secret of the shrimp's behavior by placing several shrimp
in an aquarium.
Instead of
the usual sand at the bottom, he replaced it with steel filings. When the time
came for the shrimp to molt, it reached for a piece of steel instead of the
usual grain of sand.
The
biologist then used a magnet, and immediately the shrimp flipped upside down and
continued swimming without missing a beat. Apparently the pull on the steel in
its head was stronger than the tug of gravity.
The
scientist then took a shrimp from the ocean, with the usual piece of sand in
its head, and put the shrimp into the aquarium. It was the only one who swam
the usual way, while the other shrimp were swimming upside-down!
The latter might have begun to
whisper about the newcomer, "Who does he think he is? Is he trying to impress
someone by being so different?"
That's
exactly what we humans do at times. If anyone is different from the rest of us,
we are tempted to bring about isolation, ridicule, and sometimes even bring
about persecution. One might call this peer pressure.
In our
illustration the lone shrimp acted differently from the others that were all
about him. In our society today it is easy to find ourselves going the opposite
direction. When that happens, what do you think our little grain of sand should
be?
What will keep us upright?
