Recently, I viewed a program on spiders.  One in particular that caught my 
attention lived under water for most of it's life.  It had constructed a sac 
around it's abdomen that contained air which allowed it to be under water 
for a length of time.  Any ideas on what type of spider this is?  Where can 
I find more information? Thanks in advance.
