The giant whip spiders of Africa and Arabia: broad, flat amblypygids with feeler legs spanning wider than a hand, and the gentlest large arachnids anyone keeps. No venom, no silk, no bite worth the sentence, and a tolerance for careful communal housing that makes group displays possible.
Keeping is vertical: broad cork bark, height for the hanging moult that a fall would turn fatal, warmth, and humidity. They flatten into crevices by day and stalk at night, moving sideways on legs that work like antennae.
African supply arrives in irregular pulses with modest captive breeding behind it, and within the whip spider shelf this genus is the size flagship: the largest commonly available species, priced on span and origin, delivering the most alien body plan in the hobby at essentially zero risk.
