Red : Javan Slow Loris
The population can be known through a number of illegal trade in Javanicus market. In the year 2000-2006 there were 894 head of trading from previous 1000 larvae. So it can be concluded the number of Javanicus Nycticebus which is now diminishing. This is a serious concern for preservation in the wild, given the proliferation of Slow Loris enough that only can give birth to one offspring in a year and a half. So it can be concluded the number of Javanicus Nycticebus which is now diminishing.
