Meaning and Definition
A specialized cell in sponges (phylum Porifera) that has a collar of microvilli surrounding a single flagellum, used for generating water currents and trapping food particles.
Also known as a collar cell, it is a defining feature of sponges, crucial for their filter-feeding mechanism. The beating flagellum creates water flow through the sponge's pores, while the collar traps bacteria and other nutrients.

From Greek 'choanē' (funnel) and 'kytos' (hollow vessel, cell). It refers to the funnel-shaped collar of microvilli.
Absolutely not. It is only necessary for advanced study in marine biology, zoology, or evolutionary biology.
