Nerfs were antlered mammalian herbivores raised on farms and in animal nurseries on planets such as Alderaan and Kashyyyk. They were popular for their meat, nerfmilk, and soft hide. It is suspected that they originated on Alderaan, but escaped its destruction.
In the wild, they were common prey for predators such as manka cats and taoparis. They were often hunted by sentient beings such as the Gungans.
Subspecies of nerfs included Grizmallt nerfs and wildernerfs. A number of nerf breeds were also found on the Tunroth Triumvirate worlds.
Herders of the beasts—nerfherders—were well known for being as scruffy-looking and surly as their livestock. To be called a nerfherder was considered a strong insult.
Their hide was used as a material for chairs.
There was also a crude sport involving nerfs: nerf-throwing.
