Lagidium viscacia-By Diego Carús
Lagidium viscacia, commonly known as the mountain viscacha or Andean rabbit, is a species of rodent found in the high altitude regions of the Andes mountains in South America. They are closely related to other species of viscacha in the genus Lagidium, including the plains viscacha and the southern mountain viscacha.
All species in the genus Lagidium are part of the family Chinchillidae, which also includes chinchillas and their close relatives. The family Chinchillidae is further classified within the order Rodentia, which includes all rodents such as mice, rats, and squirrels.
In terms of sister species, the mountain viscacha is most closely related to the southern mountain viscacha (Lagidium wolffsohni), with which it shares a similar geographic range and habitat preferences. The plains viscacha (Lagostomus maximus) is also a close relative, but inhabits a different type of habitat, primarily grasslands rather than rocky mountain slopes.
Overall, the mountain viscacha is a fascinating species with close taxonomic relationships to other species in its genus, as well as the broader family of chinchillas and rodents.
