Craspedida
Order of single-celled organisms
From Wikipedia, the free encyclopedia
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]
