Not to be confused with
another cell wall degrading genus Vampyrella! Vampyrellidium
has some ultrastructural similarity to Nuclearia as well
as sharing a relativily simple life history (Patterson
et al, 1987). The genus is also similar in
feeding habit to the Vampyrellid amoeba described by Old &
Darbyshire (Old & Darbyshire, 1978).
Mitochondria are similar to Nuclearia and both have golgi
surrounding the nucleus and a filamentous surface coat. The most
remarkable feature of both Vampyrellidium and
Nuclearia is a perinuclear striated band associated with
microtubules! However, Vampyrellidium is similar to Vampyrella
and differs from Nuclearia in that it feeds on algae by
penetration. A large Vampyrellid amoeba (100um
in length), has been found to be relatively common in waters around
mangrove in Florida, US. (Rogerson &
Gwaltney, 2000).
