So far this genus is
known to be exclusively marine (Page, 1983).
Paramoeba has
been placed in the family Paramoebidae along with
Mayorella and
Dactylamoeba. However,
Page (Page,
1983) was not convinced of the validity of
the genus as it stood then and preferred the Family name Mayorellidae
instead. Paramoeba permaquidensis
groups close to Acanthamoeba
according to older SSUrDNA analysis (Sogin et al
1996), however, more recent studies with
more amoeba indicate a kinship with Vannella
(Fiala & Dykova, 2003).
Members of this genus are known to be pathogenic for fish (Kent
et al, 1988; Paniagua
et al, 1998), echinoderms ( Jones
& Scheibling, 1985) and arthropods (Sprague
& Beckett, 1966). Paramoeba
has been re-named Neoparamoeba
and more details on the genus are to be found under this name.
