Capybaras are the largest rodents in the world. Yes, rodents. Think cute guinea pig, rather than sewer rat or house mouse. I recall having a guinea pig when I was quite young, named "Ralph". He wasn't very cuddly. Kinda like a wild capybara, I suppose...though I've read that it isn't unheard of for capybara to be domesticated and made into pets. Now THAT could be interesting!
I don't know if this photo is of a male and female or simply of two same-gendered capybara of differing size.
I know I'm a little front-focused in this shot. I'm hoping it doesn't distract too much.
