A is for agouti (ah GOO tee), a rodent from Central and South America rain forests that looks a bit like a really large guinea pig. Its coarse hair is covered with an oily substance that acts like a raincoat. The hair is longest on its rump. The agouti has five toes on its front feet and three on the hind feet. It walks on its toes, not flat-footed like many rodents, giving the agouti a dainty look.
Although it is hard to see it, the agouti does have a tail: it is very small, looking like a dark jelly bean stuck on the animal's rump!

I photographed the agouti in Monteverde, Costa Rica. They were everywhere much like we have squirrels roaming around our grounds.
