The Larger Relatives of the Common Cavy

These large rodents are something else. Yes, I am talking about the Capybara. Originally a wild animal, it is now a domesticated animal as well. They make wonderful outside pets, but many people choose to keep them indoors as well. And it's closest relative is...you may have guessed. The Common Cavy. Capybaras and Guinea pigs are both in the family of Caviidae, or commonly known as Cavies. These giant rodents show much resemblance to it's littler cousin. 

The Capybara is an excellent swimmer, and considered semi-aquatic mammals. They are found in almost all the countries of South America. These rodents are strict herbivores.
Does that sound familiar? It does to me. Capybaras are becoming very popular as pets across South America. They are usually gentle creature and like human-interaction. 

Personally, I would be rather afraid to have one of these animals as a pet. Would a bite from a full grown Capybara do some real damage? In recent studies, scientists are trying to find out who has the hardest bit- Squirrels, Guinea Pigs, or Rats. Researchers are almost certain that the winner is your Common Cavy. Because of it's close relation to Capybaras, they think that the Cavies may have their jaw Structure and hard-biting teeth. Capybaras use the to get semi-aquatic plants uprooted from the ground, such as seaweed.
It's amazing how closely related your little squeaker is to the largest rodent in the world.
