Agouti refers to a number of species of rodents, as well as a number of genes affecting coat coloration in several different animals.
Agouti in Rodents
The term Agouti may refer to any of several kinds of rodents including—
- those popularly called Agouti or Common Agouti (genus Dasyprocta).
- those of the genus Agouti (also called Cuniculus); mainly Agouti paca, the Paca.
- those of the family Dasyproctidae, which, besides the Common Agoutis and the Pacas, includes the Acouchis.
Agouti Coloration in General
The term agouti refers to animals with banded, or brindled, fur -- each individual guard hair is not one solid color but instead has "stripes" of (usually) black, brown and white producing an animal which is not a solid color but appears speckled or brindled. Animals commonly displaying an agouti color phase are mice and rabbits.
Agouti in Horses
The agouti gene is responsible for the bay coloring of horses. It acts on the black base coat (see Equine coat color genetics) to restrict the black only to the horse's points (mane, tail, lower legs).
