Opalomonadea Opalomonadea is a class of biciliate phagotrophic opalozoans with an anterior hairy cilium, often from anaerobic habitats. It is a monophyletic group previously known as clade MAST-12, sister to Opalinata Opalinata is a superclass of non- ph ...

Description

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

Phylogeny

The cladogram below shows the relationships between Wobblata and the rest of Opalozoans.
