Pacas are 50–77 cm (20–30 in) in length, excluding the 13–23 cm (5.1–9.1 in) short tail, weigh 6–14 kg (13–31 lb), and are the sixth-largest rodents in the world. Similar to guinea pigs, they have square heads, small ears, sides patterned with spots and stripes, and virtually invisible tails. With large hind limbs, small fore limbs, and cone-shaped bodies, pacas are similar in appearance to the deer-like, ungulate chevrotains, and like them have four to seven horizontal lines of blotches and stripes along their flanks. They have a heavy and robust appearance, though their legs are long and relatively tiny. Learn more about Paca
