The Central American agouti (Dasyprocta punctata). It is a middle size (3-4 kg.) rodent related to a guinea pig. It's a diurnal mammal living in monogamous pairs up to 20 years. It mainly forages for seeds, some leaves and shoots. It occurs from Mexico to South America. It is a vital link in seed distribution. For example the Brazilian nuts have very hard shell and only agouti is capable to crack it (there is as well a parrot, that was observed to open the shell but the parrot has no significance to the nut). Thanks to the agouti the Brazilian nuts can germinate again after opening the shell.
