Lowland paca

Species of rodentTemplate:SHORTDESC:Species of rodent

The **lowland paca** (*Cuniculus paca*), also known as the **spotted paca**, is a large rodent found in tropical and sub-tropical America, from east-central Mexico to northern Argentina, and has been introduced to Cuba and Algeria.

The animal is called ***paca*** in most of its range, but ***tepezcuintle*** (original Aztec language name) in most of Mexico and Central America, ***guardatinaja*** in Nicaragua, ***pisquinte*** in northern Costa Rica, ***jaleb*** in the Yucatán peninsula, ***conejo pintado*** in Panama, ***guanta*** in Ecuador, ***majás*** or ***picuro*** in Peru, ***jochi pintado*** in Bolivia, and ***boruga***, ***tinajo***, or ***guartinaja*** in Colombia. It is also known as the ***gibnut*** in Belize, where it is prized as a game animal, ***labba*** in Guyana, ***lapa*** in Venezuela, and ***lappe*** on the island of Trinidad. Although lowland pacas are not in danger of being extinct, local extinctions have occurred due to habitat destructions.

There is much confusion in the nomenclature of this and related species; see agouti. In particular, the popular term *agouti* or *common agouti* normally refers to species of the distinct genus *Dasyprocta* (such as the Central American agouti, *Dasyprocta punctata*). Sometimes the word *agouti* is also used for a polyphyletic grouping uniting the families Cuniculidae and Dasyproctidae, which, besides the pacas and common agoutis, includes also the acouchis (*Myoprocta*). *Cuniculus* is the appropriate genus name instead of *Agouti* based on a 1998 ruling of the International Commission on Zoological Nomenclature as the lowland paca's genus.

## Etymology

The word paca comes from a word in the Tupi language that designates the animal but also means 'awaken, alert'.
Tepezcuintle is of Nahuatl origin, meaning 'mountain-dog', from tepetl, 'mountain' + itzquintli, 'dog'.

## Description

The lowland paca has coarse fur without underfur, dark brown to black on the upper body and white or yellowish on the underbelly. It usually has three to five rows of white spots along its sides, against a dark grey background. It has thick strong legs, with four digits in the forefeet and five in the hind feet (the first and fifth are reduced); the nails function as hooves. The tail is short and hairless. The zygomatic arch is expanded laterally and dorsally and is used as a resonating chamber - a unique feature among mammals.

An adult lowland paca weighs between 6 and 12 kilograms (13 and 26 lb). Each litter has one young lowland paca, sometimes two. They usually have one to three young a year with a gestation period of about 115–120 days. Pacas are sexually mature at about 1 year. A paca usually lives up to 13 years.

The lowland paca can carry leishmaniasis and trypanosomiasis.

## Habits

The lowland paca is mostly nocturnal and solitary and does not vocalize very much. It lives in forested habitats near water, preferably smaller rivers, and dig simple burrows about 2 m (6 ft 7 in) below the surface, usually with more than one exit. It can also sometimes live in burrows created by other animals. The lowland paca is a good swimmer and usually heads for the water to escape danger, as it can stay under water for several minutes. It also is a very good climber and it searches for fruit in the trees.

The lowland paca can be considered an important seed distributor, since its diet includes leaves, stems, roots, seeds, and fruit, especially avocados, mangos and zapotes. It sometimes stores food.

## Economical and ecological aspects

The lowland paca is considered an agricultural pest for yam, cassava, sugar cane, maize and other food crops. Its meat is highly prized. It is plentiful in protected habitats, and hence not in danger of extinction, but overall its numbers have been much reduced because of hunting and habitat destruction. It is easily bred and raised in farms, although the taste is said to be inferior (perhaps unpleasant) when farmed. Some of the lowland paca predators include cats, coyotes, bush dogs, crocodiles, and boa constrictors.
