choanoflagellate

Examples of choanoflagellate in the following topics:

• Pre-Cambrian Animal Life

  • Some protist species called choanoflagellates closely resemble the choanocyte cells in the simplest animals, sponges.

• Morphology of Sponges

  • Note that there is a similarity in appearance between the sponge choanocyte and choanoflagellates (Protista).
  • This similarity suggests that sponges and choanoflagellates are closely related and probably share a recent, common ancestry.

• Constructing an Animal Phylogenetic Tree

  • Both Parazoa and Eumetazoa evolved from a common ancestral organism that resembles the modern-day protists called choanoflagellates.
