When a discosean is in motion, a transparent layer called hyaloplasm forms at the leading edge of the cell (see lamellipodium).

In some discoseans, short "subpseudopodia" may be extended from this hyaloplasm, but the granular contents of the cell do not flow into these, as in true pseudopodia.

Discosean amoebae lack hard shells, but some, like Cochliopodium and Korotnevella secrete intricate organic scales which may cover the upper (dorsal) surface of the cell.

[6] In 2011, Smirnov et al. accepted Discosea as a class, and reduced Flabellinea to the rank of a subclass with the name Flabellinia.
