A coral reef
is a collection polyps (tiny marine life forms) skeletons that form together
over time. These form the corals that we are used to seeing. However, coral is
alive, and makes its own food from a mixture of water and sunlight. Some do
feed off the cells of other marine life, using tentacles that grow from them. Many
types of fish live in the reefs and hide in the branches of the coral. They feed
from smaller fish or eat plankton. The types of fish that live in the reefs are specially designed to fit in
their surroundings. Coral is naturally bright colored, and many fish are too,
so of course the reef provides the fish with a great hiding spot. The Purple
Stonefish is a good example of marine camouflage and looks just as its name
suggest. It sits still and quiet and waits for its prey to come by. More fish
like this include the Pipefish, Hermit crab and the Yellow Sunfish. Sadly, the world’s
coral reefs may be destroyed by pollution and human interference. Coral reefs
are very fragile bits of nature and
could one day vanish. However, efforts are being made to preserve the reefs,
and hopefully survive for a long time.
