Filipodium aspidosiphoni | |
Filipodium is a genus of parasitic protozoa in the phylum Apicomplexa. Species in this genus infect marine invertebrates.
This genus was described by Hukui in 1939.[1]
Taxonomy
The type species is Filipodium ozakai.
Description
The mucron is broadly funnel shaped with papillae around its rim
The gamonts are elongate, with longitudinal striations and with many protrusible filaments emerging from beneath the pellicl
The gametocysts have numerous many oocysts
The gametes dissimilar: the male gametes not flagellated
The oocysts ellipsoidal or ovoid and have 8 sporozoites.
Life cycle
The species infects sipunculid worms.
The parasite infects the gastrointestinal tract and is presumably transmitted by the orofaecal route but the details of this mechanism are presently unknown.
Host record
- F. ozakii - Siphonosoma kumanense
