Spells: Animal Charm

[Taluvill]

Dont have a website to confirm, but was wondering if spiders and beetles and such should be considered animals?

Im a druid and have just recently started charming. Shiverbacks in PoFear work wonderfully and do work. My only question is that i remember spiders and such being considered animals and thus charmable. Was wondering because i'd love to charm Lava Duct Crawlers in Sol B.

Thanks, if you need proof i'll go hunt something down.
