Yes, but they literally did not change the model of the tapir - it's an unfinished animal. I'd also say that there's no way to really know how easy it is to change an animal's skin from Frontier's perspective. I don't take the modders at their word on this because they clearly operate on different terms.tell that to the Malayan tapir. Poor guy
In any case if you think a dromedary camel is just a different coloured Bactrian, then mate, you need to have a Google.
As to your other examples, leopards behave differently from any other cat in the game, and look very different too, so not a 'clone', and the Nile crocodile is also very different from the saltie. As I said in another post, the Arctic wolf wasn't free and wasn't thrown in, and to get the dromedary, leopard, or Nile crocodile you'd need the same amount of effort, really.
