All liquid has what is loosely called surface tension. This could be likened to the skin you get on tomato soup, except most liquid doesnt have to "go off" before it developes its skin.
Water-boatmen are so light that when they swim they do not actually penetrate the "skin" of the water. Tiny hairs on their limbs grip this "skin" in the same way the hairs on a flys' legs grip the ceiling. You could say that water-boatmen don't actually swim in water at all, but rather WALK on it!
If you want to try an experiment to test how strong the "skin" of water really is, try making yourself a cup of your favourite drink (tea for example). With the cup full, take a teaspoon and try to balance it on the rim of the cup so that the spoon end is floating in the liquid and the handle is horizontal (ish). It might take a bit of practice to get the spoons centre of gravity in exactly the right spot, but when you do you will notice that you can slowly push the spoon so that more of its weight is resting on top of the liquid. Eventually of course, the spoon will sink. This happens when it displaces a mass that is greater than its own. The same applies to water-boatmen, and all other creatures that can walk on water.

What is a water boatman?
The aquatic insect known as a water boatman is either of the family Corixidae or Notonectidae; both bugs come in variations of brown and both live in still, or nearly still, freshwater environments. Both are found worldwide; they are of the same order, Hemiptera, and so are related to aphids and cicadas. Corixidae is the family known in the US as water boatman; they swim near the bottom, on their fronts, and are mainly vegetarian. A water boatman in the UK is of the family Notonectidae; they swim close to the surface, on their backs - they're also known as 'backswimmers' - and catch live food, from insects to any fish small enough for them to tackle. They have more variety in color, with shades of green or yellow, as well as brown. The links below have more information on the varieties of these insects, and include further links with even more information.
