When the rain falls

Needles pierce the barrier of my world,
cooling the reef's exposed stomach,
where many green lives lay unfurled, 
under the gaze of a lunar lantern ever watching.

The light wavers, wilts then is enveloped,
by a shadow, a cloud, slick steel.
leading a pack, a swathe of rings, a sickly green,
mimicking the green of shells.

Mimicking the dance of prey,
arching its mouth, all-consuming
like a predator to kill however blind,
capturing all in its path.

And when again rain beats down
it falls on steel instead, 
only moving the grave remains, 
of turtles closed and curled.
