The heavyweight jumping spiders: Old World giants that carry the jumper's charisma at several times the familiar scale, with the same forward-facing eyes, the same tracking of movement beyond the glass, and the same engagement that built the jumper hobby.
The program scales up rather than changing: planted housing with structure, flying and crawling prey, gentle humidity, and the annual clock that governs all jumpers. Juveniles remain the rational purchase; adults remain a short subscription. Venom is unremarkable.
African and Asian supply arrives thinly and irregularly, captive breeding is modest, and the size premium over the familiar American jumpers buys the same behaviour in a larger chassis. When listings appear they move quickly, because the audience for a giant jumping spider is the entire jumping spider audience.
