West African wandering spiders, red-fanged in the traded species, and barely studied, which in this family argues for more caution rather than less: the wandering spiders as a group include the most medically documented spiders on earth.
Fast, nocturnal, surface-active, and containment-governed. Treated as medically relevant until shown otherwise: no handling, sealed housing, deliberate maintenance.
Thin African pulses supply a specialist trade of a few sellers, identification is soft, and the buyer pool is correctly small. The genus trades on the family's reputation and prices on its own scarcity, and the honest position is that the hobby knows the enclosure requirements better than it knows the animal.
The line on each tile: lowest ask per day.
Rarity BETA Rarity is supply, and only supply: the tier is how many sellers have ever carried a species, and for a single seller, how many separate listings. Price is not part of it, and neither is how recently it appeared. Tiers are given to tarantula species only.
