Discosea je razred Amoebozoa, koji se sastoji od golih ameba spljoštenog, diskoidnog oblika.[1] Članovi grupe ne proizvode cjevaste ili supcilinindrične pseudopodije, poput ameba klase Tubulinea. Kada su u pokretu, na prednjem rubu ćelije formira se prozirni sloj nazvan "hijaloplazma" (vidi lamelipodija). Kod nekih može se iz ove hijaloplazme proširiti kratka "subpsudopodija", ali zrnati sadržaj ćelije se u njih ne uliva kao u pravoj pseudopodiji. Diskozejskim amebama nedostaju tvrde ljušture, ali neke poput rodova Cochliopodium i Korotnevella izdvajaju zamršene organske krljušti koje mogu pokriti gornju (dorzalnu) površinu ćelije. Nijedna vrsta nema bičeva ili bičasti životni stadij.[2][3] Taksonomski sastav Discosea sličan je sastavu razreda Flabellinea, koji su 2005. predložili Aleksej Smirnov i njegovi saradnici.[4] However, Discosea is a more comprehensive taxon, including several groups not included in Flabellinea.[5] In 2011, Smirnov et al. accepted Discosea as a class, and reduced Flabellinea to the rank of a subclass with the name Flabellinia.[2]
