There are certain animal skills that I can let slide. You know, give the old, "wow, I'm so impressed. Thanks for showing me that, animal" line and get back to my taco salad (extra taco, hold the salad). But tail regeneration is just too fucking much. Honestly, these lizards can have a part of their body ripped off and then miraculously grow it back, and they act like it isn't a big deal. Well it is. It's a goddamn huge deal. Most pets are just happy having tails, but lizards take their pet awesomeness one step higher with tail regrowth.
But not only can we humans not grow our tails back, we don't even have tails. Well, at least we can regulate our body temperature.
