We don’t yet know what type of flagellate this is, and have never before seen live amoebae with flagellates inside… The flagellates appear to be trapped (or happily) inside the test. All amoeba with associated flagellates in tests were found in one sample from Acadia National Park in August 2012. |

Here, H. elegans (smaller amoeba) and H. papilio (larger amoeba) appear to be having sex. We hypothesize that these morphospecies are actually examples of sexual dimorphism. |
