Light green water above, deep green water below, green water all around. A reef covered with club-fingered coral forms a wall to the west. A wide patch of sargassum on the surface blocks the moonlight. The long, green, flat-bladed streamers hanging beneath the sargassum sway and undulate sinuously.
