This is going to be a series about various animals that have bitten me in my lifetime. You'll probably learn about a few animals you've never heard of, though I'll throw a few common ones in too.

Coendou prehensilisThe prehensile-tailed porcupine, or coendou, is the only animal that sent me to the doctor. Imagine the look on the doctor's face when I told him I had been bitten by a porcupine! (Actually, he was surprisingly blase about it. What a disappointment.) The coendou is a largish rodent that can hold onto things, such as tree branches, with its tail.

Of course, I also got lots of quills in my arm, but not to worry! Porcupine quills have a natural antibiotic property so you tend not to get an infection when you get poked. However, the doc did prescribe some major antibiotics, because rodent teeth and mouths harbor all sorts of bacteria. Yechh! The bite was not bad enough to need stitches, or even butterfly bandages. It just needed to be cleaned out really well. I handle a lot of animals as part of my zookeeping job, and this one got startled by feedback from a speaker. We wear gloves to handle porcupines (for obvious reasons), but he whipped around and latched his sharp, pointy teeth into my arm above where the welder's glove ended.
Coendou live in South America where they spend most of their time in the trees, eating all kinds of vegetation.
