"I study spider sex."
Of course, a big part of that is because I'd get really tired, really fast of having to defend my "useless" research.
I'm all for basic biological research ("really?!" You say, "I find that hard to believe") but sometimes I wonder what drew somebody to a research project in the first place.
I can't imagine writing a grant proposal or statement of purpose where you talk about how excited you are about spider sex.
That said, one thing I did find interesting in the article is that they don't actually know how the spiders detect UVB light.
