FAQ
Frequently Asked Questions
No, they are unicellular protists, but they are the closest living unicellular relatives of the animal kingdom (Metazoa).
They are found globally in aquatic environments, both freshwater and marine.
It derives from the Greek 'choanē', meaning 'funnel', referring to the funnel-shaped collar of microvilli surrounding the cell's flagellum.
They are studied primarily to understand the evolutionary transition from unicellular life to multicellular animals, as they share many genes and cell behaviors with simple animals like sponges.

Mnemonic
Imagine a tiny cell wearing a FUNNEL (choano-) as a COLLAR, using a WHIP (flagellum) to swim and eat. It's the 'collared whip' cell that's an animal cousin.
Conceptual Metaphor
A LIVING FOSSIL (conceptually representing an early stage in animal evolution).
