Cassowaries can swim!

[Catherine]

Cassowaries are the world's most dangerous bird. They are big and they have long claws that they are willing to use. 
Imagine the surprise of seeing a cassowary coming out of the ocean. This is a first.

I would be a little worried if I encountered a cassowary. I can't imagine what it would be like to see on coming out of the ocean.
Cassowaries may be dangerous, but they are also endangered. They do need our help to survive. As usual habitat loss is a problem and traffic deaths.
