Iambic pentameter

The mermaid arched its back and gave a cry
The seaweed wrapped his tendrils round my foot
‘Ah ha!’ she laughed and sank into the depths
But rest assured, I’d naught but learn to swim
So kick,  I did,  square in the mermaid’s jaw
So slick the blood that bled into the bay
Unwrapped my ankle from the slimy weed
Swam up until I pushed through crashing waves
I gasped and heaved and slowed my panting breath
Fear not the song of mermaids, or of death.
