10. Sloth

According to Wikipedia, the word that most languages use to describe the sloth means “Sleep,” “Eat,” “Dirty,” or a combination of the three. Sloths are endearing because they are really lazy and stinky and somehow retain their dignity even though they look like homeless people. I envy their steadfast ethic for my third-favorite of the Seven Deadly Sins. Now, if only there were an animal called Adultery!
9. Blue Whale
Blue whales are ridiculously huge. It is hard to even imagine how huge they are. I believe that it is worth mentioning.
8. Dobson Fly
Dobson flies are the second-most disgusting thing you will ever see. They are several inches long and have huge pincers on their faces capable of drawing blood from a human. They smell terrible because their bodies begin decomposing when they hit maturity - they are a little bit like zombies.
7. Wild Turkey
The wild turkey is a noble and underrated creature. It is nothing like a domesticated turkey. They are extremely intelligent and are excellent hunters and they have extremely lean bodies. It is often cited that Ben Franklin preferred the wild turkey over the eagle as the United States emblem - this is untrue. Franklin was unimpressed with the eagle (who “earned its living dishonestly” as Franklin put it), but did not ever officially endorse the wild turkey.
6. Penguin
Penguins are really cute. They are also super tough! If anyone has seen March of the Penguins they would understand. They withstand some pretty awful weather and just stand out in the open, taking it. I believe they escape predation by migrating to places other animals cannot survive in. Penguins maintain committed, monogamous relationships, which is pretty cool. Also, if they cannot produce their own children, couples will try to steal children from other couples - weird.
5. Angler Fish
The only thing more disgusting than a dobson fly is an angler fish. They really bother me. I find them fascinating not only because of how gross they are, but how they hunt - in the gloomy depths of the ocean, they lure prey by illuminating a tiny lantern on the edge of a stalk in front of their mouths. When an unsuspecting prey swims near the lantern, the angler will snap its mouth shut.
4. House Cat
We all love housecats. They are very friendly and they purr at you when you stroke them.
3. Wolverine
Wolverines are generally regarded as being able to defeat any other land animal in single combat. They are tenacious and never show defeat. There are many documented cases of wolverines fighing grizzly bears - on purpose. I once watched a video where a wolverine dove into a hollow log that was infested with bees. It would dart in, get stung for awhile, dart out, and repeat. It did this about a dozen times. Whenever a bee would sting the wolverine, it would die. Eventually, the wolverine had completely wiped out the entire bee colony. It had probably been stung 10,000 times. Afterwards, it sat down and feasted on delicious honeycomb.
2. Viceroy Butterfly
Most animals develop a natural defense against predation. The defense of the Monarch is that it is poisonous and foul tasting. The defense of the viceroy is that it looks like a monarch - it is not, itself, poisonous or foul tasting.  I just looked this up and it turns out that it is not true. It was disproven in 1991. The viceroy butterfly is indeed even MORE poisonous than the monarch. This is no longer my second-favorite animal, but since I have already made the list I am not going to change it >:(
1. Unicorn
The unicorn is my favorite animal. No other animal is as beautiful or compelling. A fully grown unicorn is only barely smaller than an elephant, making the unicorn the second-largest land mammal (this was observed by famous explorer Marco Polo). Unicorns are not only beautiful, but they are magical, too. Just seeing a unicorn in the wild will bring you years of wealth and good fortune. Also, the horn of a unicorn, when ground into a powder, is capable of curing any disease as well as granting eternal life. Capturing a unicorn is difficult, however. They can only be tamed by “the gentle and pensive maiden”; when the unicorn is distracted by the maiden, you have access to your narrow window of opportunity. Do keep in mind that killing a unicorn will bring you a lifetime of poverty and misfortune. If you hunt a unicorn for its horn so that you might live forever, be forewarned that your eternal life will be a miserable one. There is as of yet only a single recorded case of a unicorn willingly sacrificing its horn (and thus its life) for another. This is in the case of our lord and savior Jesus Christ, to whom a unicorn gave its horn to allow him to rise from the dead and ascend to heaven.
