Opisthokonta

Node

Node. Holozoa. Opisthokont. Flagella[edit] One common characteristic of opisthokonts is that flagellate cells, such as most animal sperm and chytrid spores, propel themselves with a single posterior flagellum.

This gives the group its name. In contrast, flagellate cells in other eukaryote groups propel themselves with one or more anterior flagella. History[edit]
