Animal Jumble : What has the head of a horse, the tail of a monkey, eyes like a chameleon, and the pouch of a kangaroo?

Question

My head and tail both equal are,
My middle slender as a bee.
Whether I stand on head or heel
Is quite the same to you or me.
But if my head should be cut off,
The matter's true, though passing strange
Directly I to nothing change.
What am I?

Answer 1

A seahorse
