Document Summary
Leeches are ectoparasites: black flies are not ectoparasites; mosquitos no, ticks are also ectoparasites, some mites are ectoparasites. Many migratory birds harbour ectoparastic flies: flat flies are one group. Are clams ectoparasites: filter feeds: adults are not, babies are (on fish -> gills mainly, glochidia are ectoparasites on fish gills and fins. Hosts often try to get rid of ticks, etc: heron -> groom and preen. Special grooming claw: beavers have one too, some parasites live inside the host (endoparasites) Deer have parasitic in brain brainworm: reproduce in deer, deer droppings carry the larvae. If moose eats an infected intermediate host: goes to brain and eats up to spinal chord and brain tissue, thus, brainworm in wrong host can kill, why does brainworm only kill moose (42:00 nov7) Robins harbour a parasitic fluke (definitive host) Ectoparasites and endoparasites have adaptions and problems too.
