Anyway, it reminded me of a post I did earlier, about the ghost shrimp. It is not really that uncommon for certain types of aquatic life
to appear to be see-through, though. It pretty much acts as a
camouflage for the water, which makes perfect sense when thinking about a
nifty defense mechanism for survival along with an easier way to catch
prey, etc. Many jellyfishes and hydrozoans have this property, as well.
Although it is not totally translucent, a good example of such, is the
poisonous "Portuguese Man-of-War." To get a better idea what this sea
creature is about, go here: exotic-life-creatures.blogspot.com/2013/08/the-poisonous-portuguese-man-of-war.html
