The related pacas were formerly included in genus Agouti, but these animals were reclassified in 1998 as genus Cuniculus. [3] The Spanish term is agutí. In Mexico, the agouti is called the sereque. [4] In Panama, it is known as the ñeque [5] and in eastern Ecuador, as the guatusa. [6] Red-rumped agouti (Dasyprocta leporina)
There is limited information available on development within the Mexican agouti. It is known that young are born precocial, and covered in fur with their eyes open. [2] [7] Female agoutis have been found to nurse pups until weaning for up to 7 weeks post-partum, but young are tolerated and remain in their territory post-weaning.
Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. [5] [6] It is responsible for the distribution of melanin pigment in mammals.[7] [8] Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment).

The Central American agouti (Dasyprocta punctata) is a species of agouti from the family Dasyproctidae. [2] The main portion of its range is from Chiapas and the Yucatan Peninsula (southern Mexico), through Central America, to northwestern Ecuador, Colombia and far western Venezuela.
They are brownish with darker spots on the upper body. The fur becomes more orange as it goes past (going down) the middle area of the animal. The ears are somewhat square in shape. The front feet have four toes and the back have three each. They can be distinguished from other agoutis by their distinct coloring.
An agouti dog, also called wolf sable. In dogs, the agouti gene is associated with various coat colors and patterns. [10]The alleles at the A locus are related to the production of agouti-signaling protein (ASIP) and determine whether an animal expresses an agouti appearance and, by controlling the distribution of pigment in individual hairs, what type of agouti.
Azara's agouti (Dasyprocta azarae) is an agouti species from the family Dasyproctidae.Found in Brazil, Paraguay, and Argentina, it is named after Spanish naturalist Félix de Azara.
Agouti (coloration), fur coloration in which each hair has alternating dark and light bands Agouti-signalling protein or ASIP, a circulating hormone encoded by the agouti gene that acts as an antagonist at melanocortin receptors
