The jackalope is a mythical animal of North American folklore (a fearsome critter) described as a jackrabbit with antelope horns. The word ''jackalope'' is a portmanteau of ''jackrabbit'' and ''antelope'', although the jackrabbit is not a rabbit, and the pronghorn is not an antelope. Many jackalope taxidermy mounts, including the original, are made with deer antlers.

Can we conclude that is there such thing as a jack rabbit?
yes
