All at sea

Like a playful cat,the sea purrs in,
Its susurrus soothing us with its softness.
Dappled white,it dances around our feet,
Clutching at our ankles with its sheathed claws.
Some roll over to have their bellies tickled,
Others shrill with delight at its gentle touch,
Younger ones squeal in alarm as it probes
Their popliteal spaces to push them down.
Yet on another day,it raced in roaring.
People stood like mice,admiring its majestic white mien.
Too late did they turn to flee.
 It pounced and swallowed its prey,
Dragging them into its feral maw.
Now in shock we stare at the shimmering images
And find it hard to believe any more.
