Industry:Natural environment
The development of superficially similar structures in unrelated organisms, e.g., the wings of insects and birds.
Industry:Natural environment
The ozone (O3) layer in the stratosphere that gives protection to the Earth's surface because of intense absorption of harmful solar ultraviolet radiation by the gas .

The World Conservation Monitoring Centre (WCMC) and NOAA maintain the Global Coral Disease Database which is populated with over 2000 records of coral diseases from approximately 155 sources. The occurrence of a disease on a coral species (or genus) was recorded for each location and date on which it was observed. A unique combination of coral species, disease, date, and location therefore constitutes a single record.
Industry:Natural environment
A feeding structure in tunicates (sea squirts) which is a type of pharyngeal gill formed into a mesh-like basket. Cilia on the gill draw water into the mouth, through the basket mesh, and out the excurrent siphon.
Industry:Natural environment
A long, narrow coral reef, roughly parallel to the shore and separated from it by a lagoon of considerable depth and width. It may lie a great distance from a continental coast. It is often interrupted by passes or channels.
Industry:Natural environment
A population or species that cannot reproduce fast enough to replace themselves. Sink populations or species are present only because immigrants compensate for excess deaths in the area. Eventually, sink species will disappear from isolated areas.
Industry:Natural environment
A species that is particularly at risk because of low or declining numbers, a small range, or for some other reason, but is not threatened or endangered.
