the variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable.
Given this being the definition for biodiversity it has to be wrong. Considering as @red river hog said all these animals are fake, man-made, therefore have no importance or desirability for the wild natural world. I think we should see this as a form of art. Hence there's also a lack of clarity when it comes to certain ''species'' as to what it now exactly is, this is basically just a mere artistic interpretation of the sculpture.
