Kivens grow up to 10cm long, and have six setae along their flanks (derived from limbs). These enable them to travel rapidly in the soil. They have no eyes, and rely on chemoreception and hearing.
They build small tunnel systems under Exantids.
Kivens eat clubtree seeds and clubplant roots, as well as leaf detritus.
Kivens are individuals, and mate whenever they meet a Kiven of the opposite gender in the months before the clubtree reproduction season.
Gestation takes two weeks, and Kivens lay three to five eggs in a hollow dug under a plant. Many females often share the same hollow. Offspring are abandoned after laying.
