Flustrina is a suborder under the order Cheilostomata of gymnolaematan Bryozoa (sea mats). The structure of the individual zooids is generally simple, a box-like chamber of calcium carbonate, the polypides reaching out through an uncalcified flexible frontal wall, often surrounded by numerous spines. Like in other gymnolaematans, their lophophore is protruded by muscles that pull on the frontal wall of the zooid.
