(Nekaris, 2003b; Nekaris, 2003a; Radhakrishna and Singh, 2004b), The lifespan of grey slender lorises and other lorisid species have not been widely researched. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests. Wild slender lorises are almost exclusively insectivorous, yet captive conspecifics are fed a primarily frugivorous diet that is likely to contribute to behavioral and health problems.
