Not quite the same. My DD#2 (not softball or basketball player) played water polo. The refs in water polo walk along the side of the pool. So, they have a very limited view of what's going on under the surface.I'm 99.9999999% sure boys/girls play waterpolo the same way.
My DD had to wear two bathing suits during games. Players on the opposing team would try to grab a shoulder strap and pull the bathing suit down.
