Status, Habitat and Habits:
Grey Slender Loris is an uncommon species. It is the smallest primate of India. As it is highly crepuscular and nocturnal which dwells in canopy, it often goes unnoticed. However, it can be located in the night by its shrill call. This species can be found in primary as well as secondary forests. It frequents both evergreen and deciduous; and moist or dry forests. 

Conservation Status:

Both the Indian subspecies of Grey Slender Loris are listed as Near Threatened in the IUCN Red List of Threatened Species (

According to IUCN Red List assessment population of this species is decreasing all over its range. There is no global estimate of its population currently. The primary threat to its existence comes from habitat loss and fragmentation owing to several anthropogenic activities. Extension of agriculture, mining, logging and residential development has caused severe damage to its habitat. Another major threat comes from illegal pet trade. Slender Loris is one of the most trafficked animals under pet trade on which there is a ban on its trafficking internationally. Illegal pet trade poses a greater threat its persistence in wild.
