These vibrant metropolises provide food and shelter for millions of species of fishes, sea turtles, crustaceans and invertebrates — making coral reefs one of Earth’s most diverse habitats. Coral reef crustaceans include the large, more familiar animals such as shrimps, lobsters, and crabs, as well as many smaller or cryptic types like amphipods, stomatopods, and copepods. Sea stars (Class Asteroida)- These animals, also known as “starfish”, are often found in sand and seagrass habitat around coral reefs as well as upon the hard reef substrate.

Together, they create such a symbiotic... 2. Some polychaetes are sedentary (sessile), while others are motile and move about freely. Shrimps are common coral reef crustaceans that come in many sizes and colors. Clown fish or also known as anemone fish lives in the anemone. Avoid touching coral reefs as it damages them and the wildlife that lives there and if we don’t bother them, they won’t bother us. Bivalves depend upon concealment and the heavy shell to keep predators at bay. (2) Tube sponges exhibit a branched body form. Fish, corals, lobsters, clams, seahorses, sponges, and sea turtles are only a few of the thousands of creatures that rely on reefs for their survival. Because of these benefits, the host grants them a special “protected” status. Some types represent an important food source for other animals, particularly reef fishes. However, a number of other factors have also been proposed that may have caused or contributed to Caribbean coral declines over the past 5 decades and the actual contribution of sea urchin “die-offs” to these declines has yet to be firmly established. They can be white, red, pink, green, blue, orange and purple. They also often cover reef surfaces in crevices between coral colonies. On coral reefs, some shrimp species called “cleaners” play a highly significant role in the life of the coral reef community, gaining food by removing parasites from fishes or other invertebrates.

Protection from storms: Coral reefs are also our first line of defense against tropical storms, helping to protect all of our coastal communities. Even a summary treatment of what is currently known about the amazing variety of form, life histories, behavior, and ecology of invertebrate animals living in coral reef habitats would fill many volumes, and a great deal remains to be learned in this area. Of the seven recognized species of sea turtles, three are regular or occasional visitors to coral reefs in some parts of the world.

These thrive along our coastlines and are very rich habitats for both plants and marine animals. More than merely a clever collaboration that has endured between some of the tiniest ocean animals and plants for some 25 million years, this mutual exchange is the reason why coral reefs are the largest structures of biological origin on Earth, and rival old-growth … Examples of hard corals include such species as elkhorn coral or brain coral. 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.
