Currently our definitions for 'symbiosis' and 'non-intimate agonism' are contradictory, while the label for the latter is less than ideal. The reason they're contradictory is that symbioses are interspecies interactions that are more or less intimate, whereas the latter is defined by a lack of or minimal intimacy. To correct this, I'd like to propose changing 'intimate agonism' to 'endosymbiotic agonism' and define it as, "An endosymbiosis that results in harm to some host organism, and benefit to some antagonist organism." We can then create a class for 'antagonist organism' that includes 'pathogen', 'parasite', 'predator', etc. as subclasses; and change the definitions for endosymbiotic parasitism/parasitoidism accordingly. Likewise, we can follow the same steps for 'intimate agonism', changing it to 'ectosymbiotic agonism', which will have 'grazing' and 'predation' as subclasses. This is consistent with the literature, as 'parasitism' and 'parasitoidism' are conceived of as being very similar to 'predation'.
I think we'll also want to specify that 'predation' is necessary for the completion of a biological function and is lethal (i.e., nutrient and energy acquisition), whereas 'parasitism' and 'parasitoidism' are typically non-lethal (parasitism) or are necessary for the completion of a stage in the life cycle (i.e., parasitoidism). I can create another issue for this though, since I think it may deserve its own discussion.
