In the first early stage you can see that everything looks almost identical everything looks the same. They all have a curved body and what almost looks like a tail. They all have a rectangle shaped head in the first stage making them almost look like birds.
In the second stage most of them still look very similar but a few start to get there shape like the fish you can start to see them more clearly and know what they look like and what they are. Now in the last sage you can clearly see what most of them are except for 3 of them which are the rabbit, the calf and the hog still look like eachother even in this third stage. Even the human looks like those three animals. So in conclusion even though they are different animals they all look the same in the early life.
