590. This short explanation of actual wolf spiders
Wolf spiders are members of the family Lycosidae, from the Ancient Greek word "λύκος" meaning "wolf". They are robust and agile hunters with excellent eyesight. They live mostly solitary and hunt alone. Some are opportunistic hunters pouncing upon prey as they find it or even chasing it over short distances. Some will wait for passing prey in or near the mouth of a burrow.
They have the third best eyesight of all spiders, only beaten by jumping spiders and huntsman spiders, and often grow to 1.38 inches (body length, not including legs)
