The Greater Guinea Pig (Cavia magna) is a large rodent mammal. It is not a pig and it does not come from Guinea.
The Greater Guinea Pig has dark fur, such as dark-brown or reddish-brown, with a creamy-white underbelly. Its whiskers are short and dark. It has two large front teeth to enable it to gnaw plants. It has dark almond-shaped eyes.
It grows to about 31 centimetres (12 inches) in length.
The Greater Guinea Pig is native to Brazil and Uruguay in South America. It prefers to live on land near the coast near moist grassland and marshes.
It is semi-aquatic, living partly in freshwater and partly on land. It has membranes, similar to webbing, between its toes to enable it to swim.
It is herbivorous, eating vegetation.
The Greater Guinea Pig is a solitary animal. It lives in tunnels and burrows underground.
The female is pregnant for about 64 days, before giving birth to 1-2 young, called pups. The pups are born precocial, which means that they are born with fur. The pups grow rapidly.
