Even with these adaptations the expected life span for our mouse-like marsupial is anywhere between 15 and 18 months. Consequently, this study sought to investigate several electrophysiological and anatomical properties of the dunnart auditory system. crassicaudata - ‘fat-tailed’ refers to the swelling at the base of the tail where fat is stored. To survive the fluctuating temperatures, the species can maintain an even body temperature with a marked diurnal temperature cycle, torpor and avoiding direct exposure.
