| | ERBzine 1485: Den Valdron: Monkey Men of Pal-ul-don |
 | | Instead, for a lot of mammals, a tail is a 'display' appendage, dogs wag their tails to signal delight, cats puff their tails to show anger and deer flash their tails to show fear. |
 | | For a prehensile tail, you need to do things for which the appendage was never originally evolved, and for which there is minimal history. |
 | | The monkey's tail, on the other hand, is actually used as an extra limb, sensitive and versatile enough to even pick up a peanut, or to support their entire weight swinging from it. |
