A Talarian hook spider was an arachnid species, with legs approximately a half meter in length.
During this time, Miles O'Brien was called in to reroute an emitter array at a starbase on Zayra IV, when he encountered twenty hook spiders in a Jefferies tube. He recalled to Reginald Barclay that this incident helped stem his fear of arachnids. (TNG: "Realm Of Fear")
Presumably, these creatures originate from Talarian space.
