Well, dang. I’m not going to bother, since Ynnad clearly won the thread. 
A duck is mine too. (But with a nic like “mallard” I guess that’s no surprise) 
I really did not need to read an article about people eating capybaras. Who could eat such a pleasant and amiable beast? It’s making me consider vegetarianism.

We are legion but mean you no harm. As long as you give us veggies.
The Platypus.
After myriad surgeries and re-assemblies since birth, I’m a collection of unmatched and bizarre-fitting parts that somehow manages to function. And as a several assholes have discovered, there are spurs, poison glands, and a variety of well-hidden defense mechanisms. And like the Platypus, the attacker’s pain won’t start immediately, but it will be extreme and long-lasting.
I’ve told a few of these stories here – even if it takes years, I settle scores.
Killer whale.
Or Cavalier King Charles spaniel.

Crows. They like to express their love by crapping on me.
Horse. Well, one half of a horse, anyway.
The top half or the bottom?
Beaver. I was surprised, but it works.
