A long time ago Mutual of Omaha's Wild Kingdom did a show on sea cucumbers. I remember Marlon Perkins saying there are more of them then there are of us, and that they move across the ocean floor in herds scavenging for fish leftovers falling from above. Sometimes on quiet nights I'll lie awake and think of them moving like silent buffalo across the ocean plains always on the lookout for their enemies the sea turtles and, in their quiet moments, wondering about the world beyond.
