Grylloblattodea is a small order of extremophile insects that live in the cold on top of mountains. Their appearance evidently puzzled the scientist who discovered them; the first species named was Grylloblatta campodeiformis, which means "It looks like a cricket, a cockroach, and a Campodea[?]" (a kind of two-pronged bristletail).
This order includes a single family with two genera and 6 species.
