 Compared to tarantulas, wolf spiders are not particularly large or ″hairy″, and so among English speakers in particular, usage eventually shifted in favour of the Theraphosidae, even though they are not closely related to the wolf spiders at all, being in a different infraorder.The name "tarantula" is also incorrectly applied to other large-bodied spiders, including the purseweb spiders or atypical tarantulas, the funnel-webs (Dipluridae and Hexathelidae), and the "dwarf tarantulas".These spiders are related to tarantulas (all being mygalomorphs), but are classified in different families.
