Jaguar

The jaguar in the present has sharp claws and teeth. They have camouflage by hiding in the shadows because of the black spots by hiding behind trees or bushes. They are big enough to catch their prey. In the future there are not many trees and bushes, so there's not many places to hide. In the future they can paralyze their prey/predators from the tail because of such a wide space. They have a sharper nose and better hearing to get their prey from such a wide variety. One thing that is really special is that they have spikes from the back so that predators don’t come from the top to hurt them.
