Top 10 Most Extreme Animals
Okay, this was on the Animal Planet like two weeks ago, and I just remembered the animals. They probably aren't in the right order.
The Most Extreme Animal:
Guanaco, Weta, Camel, Cockroach, Penguin, Polar Bears, a Bird (Can dive down at 90mph and survive), Tube Worms, and Rats.
No, those (^^^) aren't in the right order.
