The "ultimate marine-life harasser" I know looks more like this: often over-sized and over weighted, carrying a top of the line camera (often unable to take any half-decent pictures though), completely oblivious of anything around him/her when going straight to the "target", grabbing and handling marinelife he/she wants to shoot, leaving the "target" in a swirl of sediment and broken coral when moving away to the next creature on their list, often unable to handle currents and always moan about the vis.
