Craspedida is an order of choanoflagellate, with members with an exclusively organic covering. Crown group craspedids (and perhaps crown group choanoflagellates if Acanthoecida arose within Craspedida[1]) appeared 422.78 million years ago.[2] Although a previous study from 2017 recovered the divergence of the crown group choanoflagellates (craspedids) at 786.62 million years.[3]

Salpingoeca
Salpingoeca rosetta has been named for the rosette-shaped colonies formed by its cells. Recent studies show a bacterial sulfonolipid, called rosette inducing factor (RIF-1) produced by Algoriphagus machipongonensis triggers colony formation in S. rosetta.[citation needed]
