attaches somewhere and stays there

is on and off the host during part of its lifecycle

Answer 6

stays on host all the time

as long as parasite and host are alive

can’t live on its own. lives at the expense of another organism

Answer 8

free living or obligate parasite

Question 9

aberrant parasite

Answer 9

ectopic parasite

migrates to an area of the body that it would not normally go

Question 10

pseudoparasite

Answer 10

looks like a parasite but ISN’T one

Question 11

host

Answer 11

general term

harbors the parasite at some stage of its life cycle

Question 12

final host

definitive host

Answer 12

harbors ADULT stage of parasite

Question 13

intermediate host

Answer 13

animal that harbors the larval stage and is NECESSARY for parasite to complete life cycle

Question 14

transport host

paratenic host

Answer 14

accidental host/ incidental host

UNNECESSARY for completion of life cycle

Question 15

host specific singular (HSS)

Answer 15

only 1 animal will harbor the adult stage

Question 16

host specific pleural (HSP)

Answer 16

more than 1 animal can harbor that adult stage

Question 17

life cycle (LC)

Answer 17

reproduction and maturation series of a parasite

Question 18

direct life cycle

Answer 18

parasite does NOT need the use of an intermediate host but CAN use a paratenic host

Question 19

indirect life cycle

Answer 19

LC MUST use an intermediate host

Question 20

infestation

Answer 20

establishment of a parasite within or upon a host

Question 21

infective stage

Answer 21

stage the parasite can infest the final host
