Anatomy of Corals
Coral reefs consist of many diverse species of corals. These corals in turn are made up of tiny organisms called polyps. The structure of the polyps and the skeleton of the coral is a rather simple combination. A polyp is made up or two cell layers: the epidermis and the gastrodermis. The non-tissue layer between the gastrodermis and the epidermis is called the mesoglea.

Animals Associated with Coral Reefs
Coral reefs provide habitats for a large variety of organisms. These organisms rely on corals as a source of food and shelter. Some organisms that use corals through mutualism, commensalism and parasitism are within the taxonomic groups Porifera, Polychaeta, Gastropoda, Crustacea, Echinodermata and Pisces. - Click for more information.

Caribbean Coral Identification
With a little practice and a good waterproof ID chart, identifying these corals will become fun and sometimes challenging. ---
This site discusses the keys to identifying coral.

Categories and Structure of Coral Reefs
There are three basic kinds of coral reefs in the Caribbean: fringing reefs, barrier reefs and atolls. Fringing reefs are coral reefs that grow in shallow waters and border the coast closely or are separated from it by a narrow stretch of water. Fringing reefs consist of several zones that are characterized by their depth, the structure of the reef, and its plant and animal communities. These regions include the reef crest (the part of the reef the waves break over), the fore reef (the region of medium energy), and the spur and groove or buttress zone (the region of coral growth which includes rows of corals with sandy canyons or passages between each row).

Contrasts in Blue
The activities in this lesson encourage students to consider the role of temperature, sunlight, waves, and tides in the creation of unique marine environments. Students will study the dynamics of life in a coral reef and along the rocky coast of Maine.

Coral Bleaching
Coral bleaching is the whitening of coral colonies due to the loss of symbiotic zooxanthellae from the tissues of polyps. This loss exposes the white calcium carbonate skeletons of the coral colony. Corals naturally lose less than 0.1% of their zooxanthellae during processes of regulation and replacement (Brown and Ogden, 1993). - Click for more information.

Coral Diseases
Four coral conditions have been identified as diseases: white band disease (WBD), black band disease (BBD), bacterial infection, and shut down reaction (Richmond 1993). They are also susceptible to tumors and parasitic worms. These maladies are all stress related, and anthropogenic stresses can increase a coral's susceptibility to these diseases.

Coral Feeding
Corals can obtain food in a variety of ways. Reef-building corals rely on the photosynthetic products of zooxanthellae for the majority of their nutrients. However, corals also capture zooplankton for food. Corals are suspension feeders.

Corals Reproduction
Corals exhibit sexual and asexual reproduction. The coral colony expands in size by budding. Budding may be intratentacular, in which the new bud forms from the oral discs of the old polyp, as in Diploria, or extratentacular in which the new polyp forms from the base of the old polyp, as in Montastraea cavernosa.
