 Each of the slow loris species that had been identified prior to 2012 are currently listed as either " Vulnerable " or " Endangered " by the International Union for Conservation of Nature ( IUCN ) on their Red List . When they were all considered a single species , imprecise population data together with their regular occurrence in Southeast Asian animal markets combined to erroneously suggest that slow lorises were common . This manifested as incorrect Red List assessments of " Least Concern " as recently as 2000 . The three newest species are yet to be evaluated by the IUCN , although each were once thought to be subpopulations of the Bornean slow loris — which was evaluated as " Vulnerable " in 2008 . With this division of its range and population , the Bornean slow loris and the three new species face a higher risk of extinction than before .
