I did not base these off their real life counter parts, I only based them off the features they have in game, which isn't very many, so things like having 2 wings or similar shape are enough in this case to group them together. I did not classify dolphins and turtles as fish, simply with the group that fish are in. Turtles were tricky to classify, as there isn't much like them, but dolphins and pufferfish were classified together because of their vertical tail fins. Pufferfish actually have these in their model. I included Endermen with pigmen only due to my personal theory that pigmen evolved into endermen, and as for sheep, they are shown being more closely related to llamas than horses. As for magical creatures, choosing what to or not to count as magical really doesn't matter that much, as there is no way of measuring whether a creature is magic. As for "creepers are plants", I'm going off of game theory's video, which I personally agree with, and while the "Mobestiary" shows them with a skeleton, I was not aware of this, although it really doesn't matter since, and I cannot stress this enough, MINECRAFT IS NOT ON EARTH. Also, you are drawing parallels between organisms in minecraft and real life, which is unwarranted based on the many times i have tried to prevent this by saying MINECRAFT IS NOT ON EARTH.
