Entomology (Study of Bugs)/Aquatic Spider


I have a spider living under water in my pool.  I have pics and video of it moving around at 6 inches to 2 feet of depth.  All of my quick internet research indicates that dive bell spiders are native to Europe and asia.  I am in Las Vegas.  Who should I contact about this?


Without seeing at least an image of the creature, I cannot verify what you are observing.  It could easily be an aquatic insect of some kind, or a water mite, or even some kind of freshwater crustacean.

Fishing spiders (genus Dolomedes in the family Pisauridae) can dive underwater for brief periods, but must surface.  Diving is a last ditch attempt to avoid a potential predator.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
