ANIMALS: Did you know that there can be as many different types of fish in two acres of coral reef in Southeast Asia as there are species of birds on the entire continent of North America? Shocking, isn’t it? Coral reefs only make up about 1% of the ocean floor, but they house nearly 25% of life in the ocean. Animals use coral reefs either as a stopping point, like an oasis, as they travel the deep blue sea, or they live as residents at the reef. The corals themselves are the most abundant animal on the reef. They are tiny organisms called polyps, that attach themselves to the hard reef and live there forever. The reef is like a giant apartment building in New York City and the coral polyps live together in each apartment. Corals are closely related to sea anemones and sea jellies, and use their tentacles for defense and to capture their prey. Corals can be a variety of colors, white, red, pink, green, blue, orange and purple, due to natural pigments and the zooxanthellae in their tissues.
Other animals that live on the coral reef include sea urchins, sponges, sea stars, worms, fish, sharks, rays, lobster, shrimp, octopus, snails and many more. Many of these animals work together as a team like the coral polyps and zooxanthellae. This teamwork is called symbiosis. One example of symbiosis on the reef is the anemonefish and sea anemone. The sea anemone’s tentacles provide protection and safety for the fish and their eggs, while the fish protects the anemone from predators, such as butterflyfish. Sometimes anemonefish even remove parasites from their home anemone.

PEOPLE AND CORAL REEFS: Coral reef ecosystems are important for many reasons. They remove and recycle carbon dioxide, which is a gas that contributes to global warming. Reefs protect land from harsh weather by absorbing the impact from strong waves and storms. Reefs provide food, for example, lobster and conch. Coral reefs are also a huge tourist attraction. Coral reefs are a big source of biodiversity. Without the reef, many of these plants and animals would die. Some people think coral reefs may provide important medicines for people. For example, some coral skeletons can be used by humans as a bone substitute in reconstructive bone surgery. Coral reefs are also a useful educational tool. People can learn about biomes and ecosystems, and the interrelationship between organisms and their environment by studying coral reefs.
Coral reefs are being destroyed at an alarming rate. It is estimated that we have already lost 10% of the worlds reefs, and scientists say that in the next 50 years many of the coral reefs on Earth will be gone. This destruction is often connected with human activity: pollution, sewage, erosion, irresponsible fishing, poor tourism practices, and global warming.

There are some simple things that you can do to help coral reefs. Don’t put chemicals down your drain or on your lawn. Instead use biodegradable products. Even though you may be far from a coral reef ecosystem, these products end up in the watershed and may eventually pollute waters that support coral. Conserve water. The less water you use, the less runoff and wastewater eventually find their way into our oceans. Visit a coral reef! Many vacation spots have beautiful coral reefs. When you go, hire local guides. This way you’ll learn about the reef from the people who know it best. When you visit a coral reef, treat it with care, do not touch or step on the corals. Leave the animals where you found them and do not pick them up and move them. If you have an aquarium, buy fish raised in captivity, not caught in the wild. Also, don’t use live rock in your aquarium. Although this invertebrate-encrusted rock is still legally harvested in some places, its can hurt the reef habitat. Join a group that is working to protect coral reefs. Pick up trash when you see it, this way it won’t find it’s way to the ocean. Learn more about coral reefs! Surf the Internet for information about coral reefs and marine conservation organizations. After all, knowledge is power
