Choanoflagellate - Wikipedia
WEBThe choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of the animals. Choanoflagellates are collared flagellates, having a funnel shaped collar of interconnected microvilli at the base of a flagellum.
Choanoflagellates: Current Biology - Cell Press
WEBFeb 22, 2005 · By grazing on bacteria and detritus, choanoflagellates in turn feed their larger predators and return dissolved organic material to the water column. Both in number and feeding efficiency, choanoflagellates form a critical link in the microbial food chain that supports the global ecology.
Introduction to the Choanoflagellata - University of California …
WEBChoanoflagellates are almost identical in shape and function with the choanocytes , or collar cells, of sponges; these cells generate a current that draws water and food particles through the body of a sponge, and they filter out food particles with their microvilli. Choanoflagellate-like cells are also found in other animal phyla; in organisms ...
