A character who is an eight-legged venomous arachnid.

I might suggest Arachnid instead of Spider, since species designations tend to be broader (ex. Canine, Insect, Cephalopod). We can get scorpions taken care of that way, too. Good idea either way.

I'd go for the same, except scorpions tend to make for very different characters to spiders. (At least in my experience.)

Oh, sure, I agree arachnid's okay. But I also think spider's better. Spiders have a lot of properties scorpions do not, and vice versa. I could be happy grouping together most hooved things and calling it a day, but it's useful distinguishing horses and bulls right? It's also useful to distinguish a character primarily known for giant fangs, webs, and being a big and fuzzy recluse, from a character that's primarily a desert-dwelling hunter known for huge claws and a tail and stinger, and to be able to distinguish them in ways search and preferences can work with. At that level of difference, the "arachnid" group is only a scientific technicality that's not actually useful for matchmaking.

Yeah. "Species" here is only a loose best-thing-we've-got term, not intending to fit to the actual classification group geneologists call by the name "species".

I can definitely see that argument! I was thinking especially of Insect, which encompasses way more and way more varied things than even Arachnid would (bees! butterflies! mosquitoes! etc.), but it's not really very standardized at all. It's possible the wider groupings are used to avoid an overwhelming amount of options, which is important, but if specifics are just more useful, that is important to consider too.

I don't think all spiders are venomous, are they?

The overwhelming majority are venomous. The only kind of spider I know that isn't is Uloboridae (en.m.wikipedia.org), but that's about 0.5% of spider species. We can say they're venomous like we can say cats have fur (sphinx).
