Gemuendina was a very flat bottom dwelling placoderm fish that had a similar ecological niche as modern rays. Although a placoderm, the bony armour plates on Gemuendina were quite loosely connected and would not have offered as much bony protection as the plates of other placoderms. Gemuendina also lacked plates on its mouth, and instead sucked in small organisms trough star shaped tubercle scales.
