• Create coral reefs at growths of ½ inch per year

• Deposit skeleton of calcium carbonate (limestone)

• Photosynthetic and symbiotic dinoflagellates (zooxanthellae) live within coral structure and provide energy to growing coral.

• Toxins in nematocysts are quite potent

• Of the 9,000 to 10,000 cnidarians, only a handful pose a threat to humans

• In most cases, nematocysts are not strong enough to penetrate skin
