Long-tailed chinchilla

Description

The long-tailed chinchilla (Chinchilla lanigera), also called the Chilean, coastal, common, or lesser chinchilla, is one of two species of rodent from the genus Chinchilla: the other species being C. chinchilla. Both species are endangered in the wild after historically being hunted for their soft hair coats. Domestic breeds of chinchilla are believed to descend from specimens of C. lanigera. Domestic chinchillas come in three types: la plata, costina, and raton. Historically, Chilean chinchillas were reported from Talca, Chile, north to Peru, and also eastward, from Chilean coastal hills, throughout low mountains. No fossils of the Chilean chinchilla are known to have been found, and by the mid-19th century, Chilean chinchillas were not found south of the Choapa River in central Chile. Wild populations of Chilean chinchillas, as of 1996, occurred in Aucó, near Illapel, IV Región, Chile, in Reserva Nacional Las Chinchillas and in La Higuera, Chile, about 100 km north of Coquimbo The word lanigera translates into 'bearing a woolen coat', yet chinchillas do not have a woolen coat, but instead one consisting of hair. Chinchilla's hair color was originally mottled yellow-gray in the wild. Through selective breeding, their dominant colors include beige, white, and ebony, and the recessive colors include sapphire, violet, charcoal, and velvet.Their hair is 2–4 cm (0.79–1.57 in) long. It is silky, extremely soft, and firmly adhered to the skin. Up to 75 hairs, 5–11 mm (0.20–0.43 in) in diameter, emerge together from a single hair follicle. Vibrissae (whiskers) are abundant, strong, and long—100–130 mm (3.9–5.1 in)—and emerge from single follicles. The general color of their upper parts is bluish or silvery gray; the underparts are yellowish-white. The tail has long, coarse, gray and black hairs on its dorsal surface—30–40 mm (1.2–1.6 in) long near the body; 50–60 mm (2.0–2.4 in) long near the tip—and form a bristly tuft that exceeds the animal's vertebrae by 50 mm (2.0 in). Chinchillas have a vertical split pupil in both eyes. They also have fleshy foot pads, which are known as pallipes. They can move the toes on their forelimbs to grasp things. Their hindlimbs tend to be longer than their forelimbs, like rabbits.
