wobblata wobblata wobblata is a paraphyletic grouping of all placidozoans except opalinata. it unites the classes placididea, nanomonadea and opalomonadea. wobblata scientific classification domain: eukaryota clade: diaphoretickes clade: sar clade: stramenopiles phylum: bigyra infraphylum: placidozoa superclass: wobblatacavalier-smith 2013 classes placididea nanomonadea opalomonadea 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 shows the relationships between wobblata and the rest of opalozoans. opalozoa placidozoa opalinata opalinea blastocystea opalomonadea nanomonadea placididea bikosea pseudodendromonadida bicoecida anoecida borokida rictida "wobblata"
