The kultarr (Antechinomys laniger) is a small marsupial that inhabits arid and semi‐arid areas of central Australia. The kultarr is the only species within its genus and is morphologically unique from other dasyurids. Like many Australian marsupials, the kultarr has undergone significant population declines and although it is listed as “least concern” on the IUCN red list little is known of their ecology in the wild. A lack of knowledge on their biology can be attributed to their cryptic nature and sparse population densities. Recent studies of kultarrs have increased knowledge of the biology and captive management, with current data predominately coming from captive colonies. Captive studies of the kultarr have provided data on reproduction, diet choice, nutrition, health, and disease. Kultarrs are polyestrous seasonal breeders and are believed to be mostly insectivorous.Diseases noted in captive individuals provide some insight into those that may influence animals in the wild. Further research is required on both wild and captive populations to increase the knowledge base and determine appropriate management techniques for both wild and captive populations.
