The Institute for Marine Remote Sensing (imars) at the University of South Florida is funded by the Oceanography Program of the National Aeronautics and Space Administration (NASA) to provide an exhaustive worldwide inventory of coral reefs using high-resolution satellite imagery. The project uses Landsat 7 satellite imagery to map the extent and diversity of coral reefs worldwide at geomorphological levels .

Industry:Natural environment
A stage in the jellyfish life cycle. Free-swimming scyphozoan (true jellyfishes) medusae produce gametes which give rise to small polyps called scyphistomae. After a period of growth, a scyphistoma divides transversely to become a strobila that resembles a stack of discs. Each of the "discs" becomes an ephyra larva, detaches from the strobila and swims freely in the plankton. The ephyra larva will eventually grow into an adult medusa.
Industry:Natural environment
A warm, shallow, quiet waterway separated from the open sea by a reef crest.

Black corals are colonial cnidarians in the Order Antipatharia. They are found throughout the world+s oceans, but are most common in tropical deep water habitats from 30-80 m depth. These species of black coral have rigid, erect skeletons that form branched, bush-like colonies. Black coral is commercially harvested primarily for jewelry, and may be globally threatened in many parts of the world as a result of over-harvesting.
