Document Summary
Biol 350 lecture 18 - 07/11/2017- student lecture: introduction to parasitism. Conventional term: lives on or in (and benefits, causes harm. Parasites are not a taxa it is a lifestyle. Tapeworm (cestode)- get them from contaminated water, uncooked meat. As a fetus we live inside our mother, we steal her nutrients, sometimes cause some harm: all mammals are parasitic at least at some point in their life cycle. Parasites make up the majority of life styles. Just got to physically filter water (with like pantyhose) Shared environment: lots of contact over time.

Pre-adapted: feeding attachment, some morphological feature about that organism has to already exist. If you have an attachment that allows for feeding, if it can be modified a bit for attachment for a (cid:374)e(cid:449) host, the(cid:374) you"re (cid:272)hilli(cid:374)g. Example phoresy: fish = phoretic, using another organism to catch a ride on.
