The California trapdoor spider: a stout, glossy burrower that digs a thick-walled shaft in hard ground and caps it with a heavy cork door it holds shut against intruders with startling force.
Keeping is a hillside in a container: deep, firm, moisture-holding substrate, a stable corner, and years of a door that occasionally resists you. Females live a decade or more. Venom is unremarkable, and handling has nothing to offer either party.
The market is the trapdoor market in its purest form: seasonal wandering males with months of life remaining and listings that rarely say so, against scarce long-lived females that are the only purchase worth making at any patience. The genus sells permanence, and the buyer's whole job is confirming which sex, and therefore how much permanence, is actually on offer.
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.
