Not a genus but a family: the Asian funnel-web spiders, whose members build extensive silk funnels from crevices and defend them with speed and visible fangs. A key at this rank means a funnel-web identified no further than its family.
The caution is inherited and real. Documented bites from the family's well-known members produce significant systemic symptoms, and undocumented material is treated accordingly: no handling of any kind, sealed maintenance, and respect for an animal that meets disturbance at the funnel mouth rather than retreating.
Keeping is a crevice with silk rights: cork or stone anchor, moderate humidity, prey to the funnel. Material listed at family rank is usually Chinese or Southeast Asian import stock awaiting placement, identification rests on the photographs, and prices form without anchors, as they always do at this altitude of vagueness.
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.
