WebSharks cope with the salty water by generating lots of the chemical urea. This substance, produced throughout the shark's body, counterbalances the salt in the ocean water. In other words, there's as much salt in the seawater as there is urea (and other chemicals) in the water inside the shark's tissues. So sharks don't lose water the way fish do.
