Quick Summary

Cercozoa are a diverse group of eukaryotes characterized by thin, often microtubule-reinforced pseudopods (filopods) that are used for capturing prey and selecting food. They are part of the Rhizaria supergroup, which also includes foraminifera and radiolarians. Cercozoa typically possess tubular mitochondrial cristae, and cysts are common within this group. Their kinetosomes connect to the nucleus via the cytoskeleton, and they usually contain microbodies and extrusomes.12
