Definition
Host and mutualist depend on each other physiologically
both benefit |

Definition
"Eating at the same table"
Allows commensal to feed on substances captured or ingested by host
No harm to host |
|
|
Term
|
Definition
Parasite physiologically depends on host
Usually harms or lives at host expense
(robs nutrition, mechanically, immune response) |

Term
| Accidental/Incidental Parasite |
|
Definition
Parasites that enter or attach to abnormal host, usually do not survive. May be very pathogenic
(Toxocara)
|
|
|
Term
|
Definition
Insects that feed on host during immature stages and kill host at development completion
(insects parasites of other insects) |
|
|
Term
|
Definition
Organisms is parasitic only during larval stages and free-living as adults
(rabbit bot fly) |
|
|
Term
|
Definition
| Parasite reaches sexual maturity or reproduction in host |

|
Term
|
Definition
Host is required for development of parasite
Temporary development enviornment but no sexual maturity is reached
(heartworm, malaria) |

Term
|
Definition
No development occurs Not necessary for life cycle
Temporary veichle for reaching definitive host

|
Definition
Spectrum: Amount of host for a parasite; parasite perspective
Richness: Amount of parasites for a host; host perspective |
