The Mendoza tuco-tuco (Ctenomys mendocinus) is a species of rodent in the family Ctenomyidae.[2]
Description
Ctenomys mendocinus ranges from 230–280 mm in body length, and tail length of 70–91 mm. Body mass ranges anywhere between 100-250 g, with males typically larger than females. They have a stocky, robust body shape with short limbs and ears. Pelage is predominantly light-brown with subtle black and white coloration on its dorsal side, and a lightly colored tail. Forelimbs have long claws, necessary for burrowing.[3]
Distribution
The species is endemic to the northern and central regions of the Mendoza province in Argentina, at a range of elevation from 460–3600 m.[3]
Behavior
Members of this species engage in solitary burrowing behavior. Their foreleg claws are their primary method of digging tunnels through the ground, although the incisors may be used occasionally.[3] They generally do not arise above the surface during the day time; however, they have a preference for above ground plant material and will surface to forage for food.[4]
Newborns are highly altricial: after a 3-month gestation period, pups are born half-naked and blind, weaning 56 days after birth and becoming independent after 80 days.[5]
Diet
The Mendoza tuco-tuco is an herbivore that feeds preferentially on grasses. Populations in the Andean Precordilla region of Mendoza display high selectivity for grasses and avoidance of shrubs with a preference for above ground plant material, despite a fossorial lifestyle and harsh environmental conditions that lower food availability.[4]
