Figure 1.

ML tree of Zoopagales inferred from 18S data. Nodes with >90% bootstrap support and/or Bayesian posterior probability values >0.95 are in bold. Tip labels of new sequences are in bold. For ease of reading, support values are not displayed for internal branches of the Acaulopage clade. Clades without a Bayesian posterior probability did not appear in the Bayesian consensus tree. Major clades within Zoopagales have been labeled, and a silhouette of their prey/host placed beside their label. All silhouettes were downloaded from phylopic.org. The silhouette of the rotifer was created by Ferando Carezzano. The silhouettes of the nematode and amoeba are copyrighted by Gareth Monger under a creative commons attributation 3.0 unported license (http://creativecommons.org/licenses/by/3.0/).
