The Maldive Shark by Herman Melville

The Maldive Shark
By Herman Melville

About the Shark, phlegmatical one,
Pale sot of the Maldive sea,
The sleek little pilot-fish, azure and slim,
How alert in attendance be.
From his saw-pit of mouth, from his charnel of maw
They have nothing of harm to dread,
But liquidly glide on his ghastly flank
Or before his Gorgonian head;
Or lurk in the port of serrated teeth
In white tripple tiers of glittering gates,
And there find a haven while peril's abroad,
An asylum in jaws of the Fates!
They are friends; and friendly they guide him to prey,
Yet never partake of the treat -
Eyes and brains to the dotard lethargic and dull,
Pale ravener of of horrible meat.
