Filipodium is a genus of parasites in the phylum Apicomplexa.
Species in this genus infect marine invertebrates.
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 pellicle.
The parasite infects the gastrointestinal tract and is presumably transmitted by the orofaecal route but the details of this mechanism are presently unknown.
