Phylogenetic Tree
Interestingly enough, not all scientists agree on the exact Phylogenetic tree of the Phylum Rotifera. As a result, I have drawn two potential Phylogenetic trees that were found in different sources, as well as briefly explained their differences.
Phylogenetic Tree #1Phylogenetic Tree #1 shows the Phylum Rotifera diverging into several different branches. The Acanthocephala, Seisonidea, and Bdelloidea branches are shown above. Below this are the Ploima, Flosculariacea, and Collothecacea branches, which are all shown to possess a common ancestor. Include in this Phylogenetic tree are several species types that these branches include.

Phylogenetic Tree #2Phylogenetic Tree #2 shows the Phylum Rotifera diverging into two separate classes: the Eurotatoria and the Pararotatoria. The Eurotatoria then separates into the Bdelloidea, Collothecacea, Flosculariaceae, and Ploima branches, with the Pararotatoria leading onto the Seisonacea. Interestingly enough, the Acanthocephala branch is not present, meaning that either it is not considered to be Rotifera, or is folded into a separate branch. My personal opinion is that this one is more accurate than the first one, as this one was created in the 2010s, whereas the earlier one was created and refined over the late 1990s and the early 2000s.
