Lyncodon patagonicus has a distribution within the Neotropical region. Its range is from the southern and western parts of Argentina into Chile Redford and Eisenberg, There is not a lot known about the habitat of L.
The little research there is on this species suggests that Patagonian weasels are found in Pampas habitats that have light-colored substrates excluding deserts Gittleman, The head and body length of Lyncodon patagonicus ranges from to mm, with the tail adding an additional 60 to 90 mm Nowak, They have very small ears that are covered by the surrounding fur.
Generally, the the fur is whitish with some dark brown and black tones intermixed.
From patagomicus top of the head to along its backside there is a distinguishable broad white or yellowish band of fur. Pztagonicus patagonicus has short legs, a long body, and a short bushy tail Redford and Eisenberg, The mating system and behavior of Patagonian weasles remains unknown at this time. However, most mustelids associate only briefly during the mating season.
Males have territories that overlap with those of several patagonicuus and they monitor their reproductive state through chemical cues. The reproductive behavior of this species has not been characterized. Parental care in L.
As in all mammals, the female nurses her young. Mustelids in general produce altricial young, which reside in a den or burrow until their eyes are open and they are able to walk. At this time, young weasels typically accompany their mother on foraging trips.

Patagonian weasels have been noted to enter burrows of Ctenomys and Microcavia in pursuit of prey. A defensive behavior of this species is that when it is cornered, the neck pelage will be erected.
It is reportedly active at dusk and at night. Redford and Eisenberg, The specific food habits of Patagonian weasels are little known, but the fact that this species has reduced molars and well-formed carnassials suggests that it is primarily carnivorous Ewer, Because the dietary habits of this animal are not known, it is difficult to speculate on the role it plays within its ecosystem.
This weasel has reportedly been kept by some ranchers as a working pet to destroy rats Nowak, Although this species has no special status, it is reportedly rare in Chile Nowak, This animal has not been extensively studied resulting in very little lyncoron information. In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends.
Synapomorphy of the Bilateria.
Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes.
