Craspedida is an order of choanoflagellate, with members with an exclusively organic covering.
S. 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]
