Feeding on large particulates inTracheloraphis species has been observed in living specimens to occuralong the nonciliated glabrous stripe rather than at the narrow anterior end. The absence of specialized oral kinetids in this region indicates that feeding occurs by some form of membrane infolding. Organisms were cultured using cooked egg yolk as the sole source of added nutrient, enabling the observation of the feeding process in these relatively primitive ciliates.
