Armed and dangerous: Cassowaries have three-toed feet with extremely sharp claws. The claw on their second toe is particularly deadly, as it can grow to be 5 inches long! Imagine being kicked by one of these birds (which they are known to do). Their powerful legs combined with their razor-sharp talons makes them one of the deadliest birds on Earth.
