03 Jan 13 . Back in the first half of the 70s I spent my time in a hyperbaric lab doing research in decompression sickness, 4 years of which it was in a lab of my design and construct. Those were some of the best years of my career, and I often think of what might have been, as opposed to what actually was, had the Director of our Institute been of a different mindset. In short, he took everything he could from his employees and then got rid of them. In the process he spawned several good careers for others although I know that wasn't his intent. That brings us to the first part of today's submission, that of looking at a sea creature, the sea cucumber, Isostichopus fuscus. Normally found crawling along the bottom of the intertidal zone, they are easy prey for those feeding on them except for their habit of eviscerating themselves letting the predator eat the eviscerate while the animal leaves the scene. When frightened for any reason, this is a typical response. At the Poulsbo Marine Science Center they have one you are allowed to pick up and literally take out of the water. They do observe you carefully so as to not get the critter so disturbed that it does the escape trick. While we were visiting last week the grand daughters were looking at it and one actually held it for a while partially out of the water. Apparently the number of folks playing with it actually did over stress it while it didn't eviscerate, it managed to form a large air bubble (think decompression sickness) at the ventral end. For the last 30 minutes of our visit it was floating around the tank head down and tush up which no one there had ever seen occur before. On our next trip I'm gong to be inquiring as to how it fared. The tank in which it lives is relatively shallow, and as there is no current moving the water around, it gets a bit clutter with debris including a lot of air bubbles on the surface. The result was that the photos were not quite as good as I would have desired. Enter a new software product, the second part of this tome. Perfect Photo Suite 7 has a filter called magic ocean, and it really helped make this image presentable. Although designed I'm sure to deal with the loss of red light as the water depth increases, it worked well even in this shallow tank environment. For those of you without Photoshop due to its price, I recommend you look into this product. That said, have a look at a sea cucumber floating around in a touch me tank.
