I added the hyperlinks for the benefit of any readers who have no idea what those terms mean. In a face-to-face conversation, if my interlocutor responded by asking “huh? ‘wolf spider’, ‘fishing spider’, what is that? I’ve never heard of these things”, then I could explain to them what the terms refer to; or we could use a smartphone or computer to access the very same Wikipedia pages which I linked to in my comment.
In any case you may feel free to mentally strip out the hyperlinks—that will not change my point, which is that any good-faith interlocutor will understand from the quoted comment (possibly after asking for an explanation, to rectify a total lack of domain knowledge) that the terms “wolf spider” and “fishing spider” refer to a pair of disjoint categories, and that my inquiry is into the question of which (if either!) of the two categories any given actual spider ought properly to be placed in.
