Whenever you die swimming, your player hitbox shrinks from two blocks vertically down to one block. You can only hit the person by aiming for the legs. The head, torso, and arms appear to be normal but you can't hit them, they don't seem to have a hitbox. Plus, you can fit in tight spaces that are one block tall but die of suffocation.
