Craft in nature

Superb indeed  is the Nature.

So many species and varieties exist on our earth.

But each one has its own individual and distinguishing features. And those distinctions are meant for certain purposes.

Take for instance , the Cactus in the picture has leaves in the form of spines all over the body of the green stem which is again globular in shape.  The specific nature is it adapt to the very dry climate also where the loss of water from the plant will be minimal owing to the tiny and spiny leaves.
