Bird Or Fish? Poem by David Taylor

The penguin’s graceful, swim
So powerful through the waters skim
No fear has this warm hearted bird
Rushing to find the huddled herd
Where no leopard seal will bark
In the waters, cold and dark.
And a fish with such long nose
Stealthily it fighting goes
Toothless in its older years
Only mako sharks it fears.
What I want to know
Is a penguin faster though
Than a swordfish
as it through the waters goes
And which is mightier, I wonder which
The penguin a warm hearted bird
Or the sword of a cold blooded fish.
Who can truly tell me this?
