in 1996 due to an approximately 20% decrease in the population over the previous ten years. This has been caused by intense hunting and the loss of habitat. However, the negative trend has not persisted, and both species are now listed as Species of Least Concern. The coat of these rodents is known to glow a fluorescent color when viewed under black light.
Vocalisations
This rodent has a range of vocalizations at its disposal. They can grunt and pleat. They also have a piping contact call.
