Here's why it's able to do this:
* Air bubble: It creates a diving bell around itself by trapping air in its hairs. This bubble acts like a miniature scuba tank, providing oxygen and allowing the spider to stay submerged for extended periods.
* Surface tension: Like many insects that walk on water, the water spider uses the surface tension of the water to distribute its weight and prevent it from sinking.
