This unicorn of the sea
They possess each a spiral tusk
Visible when they surface
They spar as if dueling sabres
Majestic arctic denizens
They can dive down great depths
To find food in a polar world
A world sparse and unrelenting
Named for their textured hide
Like that of a rotting corpse
Living near these icy flows
They graze on the squid and fish
She was tormented by her spouse
Her hair made loose by his pursuit
She fell into the polar sea, alas
Her hair spread out in disarray
A maelstrom began to twist it so
Its braiding formed an ivory tusk
She descended 'neath the waves
And the woman, she is the narwhal
