@Coelacanth18: Has there ever been a "demand" for any sloths?
Given the popularity of three-toed sloths in the public (think of all the "OMG how cute" videos, memes, plush toys, The Croods merchandise of "Belt" etc.), DWA seems to address a market gap, explaining its advertisement. And learning how to keep difficult species alive in captivity might be beneficial in worst-case scenarios when ex-situ husbandry might be the only option left. Pangolins might be such an example.
I agree Batto. I like that the DWA is trying to help pave the way for other facilities to one day keep them. The maned three-toed sloth is endangered, so learning how to maintain the pale-throated species in captivity could turn out to be very beneficial. And great example... I love pangolins!
I just meant that they are difficult to care for in captivity, and outside of the DWA there isn't much of a push to establish a captive breeding population. In fact, the 2009 Regional Collection Plan published by the AZA Pangolin, Aardvark, and Xenarthran Taxon Advisory Group recommends phasing them out. Quote from the report:
"At the time of the 2007 Space Survey there were three additional species reported in respondents’ collections that have been
designated as Phase Out species. These are the Pale-throated sloth, Bradypus tridactylus (1.0 in 1 institution), Hairy armadillo
Chaetophractus villosus (2.1.0 in 2 institutions), and Mexican tamandua, Tamandua mexicana (2.1.1 in 2 institutions). Given the
very small current holdings (and implicit limitations of founder base), lack of interest by other survey respondents, and similarity to
other managed species (for which genetically and demographically viable populations can be established), each has allocated a target
population of zero." (p. 31)
