Cassowaries are 5.5 foot tall flightless birds. They are native to Australia and New Guinea. They have 5 inch long dagger-like claws on their middle toes, and are known for their powerful kick. Cassowaries also communicate with low frequency calls, barely on the edge of human hearing. This is believed to be related to the large, spongy crests on the tops of their heads. In the wild, Cassowaries live to be 40-50 years old. They are also basically monsters.
