What kind of lifecycle do monogenes have?
Direct
How specific are monogenes in their host choice?
Extremely specific
What special adaptation is tailored to their hosts?
The Haptor on posterior end - finely tuned to attach to only a specific host
What is their basic lifecycle?
Eggs hatch into oncomiricidium, swim to fish host, embed on fish host.
What is the primary group infected by monogenes?
Fish
Udonella
Hyperparasite of parasitic copepod
Lays eggs on host
Polystoma integerrimum
infects amphibians
eggs hatch in water, oncomiricidium attaches to tadpool gills
Migrates to bladder and stops developing while frog on land
When frog lays eggs in water parasite eggs come out too
Parasite reads sex hormones to determine when to mature
Neotony (sexual maturity when you look like a larvae)
Gyrodactylus
Produce asexually and very rapidly
Russian nesting doll parasite
Build up very fast on hosts
No oncomiricidium stage, so must be close to hosts
Macroparasite
