Another Sphinx Riddle Poem by Francie Lynch

What flies higher and faster than an eagle;
Can move underwater in distances greater than a whale,
And quicker than a shark;
On land, makes the chetah look immobile;
Can burrow deeper, and more effectively than a mole;
Is more powerful than elephant, rhino or bear;
Has a higher perspective than a giraffe;
And presents with more audacity than a monkey;
Yet has the discerning powers of a gnat,
And the future longevity of a fruit fly?
