Who Hosts Whom?
Host that supports clonal amplification but not sexual reproduction.
What is an intermediate host?
Environmentally resistant transmissive stage.
What is a cyst?
Posterior attachment organ of monogeneans.
What is the opisthaptor?
Germinative zone producing all cestode proglottids.
What is the neck?
Fixed adult somatic cell number in nematodes.
What is eutely?
Host that supports partial development but prevents onward transmission.
What is an accidental host?
Adhesion-based motility system of apicomplexans.
What is the glideosome?
Syncytial, metabolically active body covering of parasitic platyhelminthes.
What is the tegument (neodermis)?
Linear chain of reproductive segments forming the cestode body.
What is the strobila?
Fluid-filled cavity providing hydrostatic support in nematodes.
What is the pseudocoelom?
Host that accumulate parasites, but no development or reproduction takes place.
What is a paratenic host?
Asexual division producing many daughter cells from one parent cell.
What is multiple fission?
Free-swimming digenean larva infective to molluscs.
What is a miracidium?
Hair-like tegumental projections enabling nutrient uptake in tapeworms.
What are microtriches?
Arthropod feeders that repeatedly switch hosts rather than remaining attached.
What are micropredators?
Transmission explicitly driven by predator–prey interactions.
What is trophic transmission?
Pulsating vesicle responsible for osmoregulation in many protists.
What is the contractile vacuole?
End product of digenean polyembryony that exits the snail host.
What is a cercaria?
Fluid-filled canal system within the hypodermis of the body wall of acanthocephalans.
What is the lacunar system?
Barbed anchoring structure in ticks.
What is the hypostome?
This animal (common name) serves both as vector and definitive host for Plasmodium spp. parasites.
What is the mosquito?
Temporary nuclear exchange between protists without full cellular fusion.
What is conjugation?
Ventral saucer-shaped attachment organ of digeneans.
What is the acetabulum?
Larval stage of cestodes that develop in a crustacean (first intermediate host) and are infective to fish (second intermediate host).
What is the procercoid?
Arthropod developmental transformation mediated by successive molts.
What is metamorphosis?
