“The IUCN Red List of Threatened Species provides taxonomic, conservation status and distribution information on taxa that have been globally evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those taxa that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable).” Records include classification, assessment information, geographic distribution, summary documentation, detailed documentation and data sources. Advanced searching allows for limiting by region, country, marine region, or biome. Records do not contain images, but the site does refer visitors to a list of links organized by organism (i.e. mammals, fish, birds, plants).
