Behavior of Captive Loris Tardigradus Nordicus: A Qualitative Description, Including Some Information about Morphological Bases of Behavior

  • Helga Schulze
  • Bernhard Meier


In 1980, a captive breeding program for Loris tardigradus nordicus was started at the Ruhr-University (Meier, 1989). Experience showed that successful husbandry and breeding of slender lorises is not difficult if the behavioral needs of the animals are taken into account. On the other hand, the species is very susceptible to improper captive conditions which easily lead to reproductive failure or deaths. This paper was written to provide knowledge about slender loris behavior which might also contribute to better husbandry conditions.
