The only member of the
genus Pernina to date is Pernina chaumonti (El
Kadiri, G. & Joyon, L. 1992). The
position of Pernina chaumonti is not presently clear but this
amoeba has features of the Vahlkampfiidae being limax. An oddity
of this marine amoeba is that depite the fact that it originated from a
fully marine environment and it cannot tolerate dilute media, the amoeba
is able to form a cyst. Pernina is also phycophagous
being able to ingest Porphyridium. No flagellate stage
was seen.
