Resumen:
Semiaquatic habits evolved in several Sigmodontinaerodent species, but this issue remains poorlystudied. The marsh rat Holochilus vulpinus (Brants, 1827)has been associated with palustrine wetland environmentsand exhibits several morphological traits relatedto the semiaquatic habit. However, its swimming behaviorand the way its morphological specializations contributeto it have not been evaluated so far in this species. Thisnote focuses on describing and quantifying the swimmingbehavior and swimming performance of H. vulpinus.In order to address these issues, five individuals ofH. vulpinus, four adults and one subadult, were filmedwhile swimming and their performance was quantified.The obtained results indicate that the swimming mode isbipedal paddling, alternating the stroke of the hind feet.The quantitative indicators also qualify H. vulpinus as agood swimmer compared to other terrestrial and semiaquaticmammals.
