Ellobiopsidae-what is it?

Further to what Paul Hargraves has said, Margulis et al. (1990) have a chapter
by Howard C. Whisler on these strange beings. Ellobiopsida are said to be of
uncertain affinities (Incertae sedis) and to include "some of the most dramatic
and enigmatic of parasites in the marine zooplankton". The author goes on to say
"These heterotrophic, coenocytic organisms parasitize euphasids, mysids,
amphipods, shrimp, and copepods... They display features that have led various
workers to relate them to either the fungi, algae, or protozoa."

Hi Linda,
        The ellobiopsids are one of many "incertae cedis" groups.  Noone
really knows what their phylogenetic affinities are.  However, it
appears to be reasonably certain that their prior inclusion in the
Pyrrhophyta is incorrect; i.e., they are not dinoflagellates. Surely, a prime
disseration topic for a student lurking
out there.  Ellobiopsids get a mention in the current conventional wisdom

fossil dinoflagellates. Micropaleontology Spec. Pub. 7,  351p.(ISSN
