Members of this group are ancestrally aerobicphagotrophic biciliates.[1] They have tubular mitochondrial cristae and a hairy anterior cilium.[1] They have a split right microtubular root,[1] i.e. one of the two (left and right) microtubular roots that support the feeding groove is split in two.[2] They lack a cytopharynx, and some of them have lost their anterior cilium.[1]
