Is a river like an animal?

This is a poem I wrote:
Would you see a river as an animal?
Roaring like a bear,
Zooming like a cheetah,
Joining rivers like a zebra in a herd,
Singing like a canary,
Twisting like a snake,
Expending territory like a lion's pride,
Howling like a wolf,
Slowing like a snail,
Raising tides like a bird's first flight,
Now you can see,
There's a lot more to a river
Than you'd think!
