Data Deficient species can contribute to high uncertainty in estimates of levels of extinction risk across groups due to their unknown risk status (Bland et al. 2. As of September 2016, the International Union for Conservation of Nature (IUCN) lists 3191 data deficient fish species. They predict that half are threatened with extinction and nearly 500 are endangered or critically endangered, mainly in South America and Southeast Asia. Consequently, a complete assessment cannot be performed. Data Deficient (DD) is a category applied by the IUCN, other agencies and individuals to a species when the available information is not sufficient for a proper assessment of conservation status to be made. All 63 globally Data Deficient bird species lack sufficient information on population size, trends, distribution and/or threats to assess Data Deficient (DD) is a category applied by the IUCN, other agencies and individuals to a species when the available information is not sufficient for a proper assessment of conservation status to be made.

González-del-Pliego et al. The information about the species is so uncertain that both Least Concern (LC) and Critically Endangered (CR) are plausible cate Serum-immunological data published 45 yrs ago, suggesting a sister species status of the then still-undescribed species to C. rugosa, were recently corroborated by mitochondrial DNA technology.

Scientists have described a new species of the Philippine false gecko, a genus found nowhere else on Earth. This does not 2010). predict the extinction risk of almost 2,200 data-deficient amphibian species.
