03 / The rarity spectrum BETA

How often do you
see the extraordinary?

From everyday favorites to almost-never-seen. A lens on market availability — not conservation status or care difficulty. Each tier opens the catalog filtered to it.

Mythic in tracked listings Almost never 1 seller, 1 listing Almost never listed. Usually one animal at one seller. 135 species Legendary in tracked listings Few and far 1 seller with 2+ listings, or 2 sellers Only a handful of sellers have ever carried it. 61 species Rare in tracked listings Worth watching 3-4 sellers A few sellers, and it does not stay listed long. 95 species Uncommon in tracked listings Occasional 5-8 sellers Around, but you will shop several sellers to find one. 104 species Common in tracked listings Often seen 9-15 sellers Usually somebody has one. 83 species Ubiquitous in tracked listings Always around 16+ sellers Everywhere, almost always in stock. 106 species
Tier
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.
One listing
One product page at one seller. Every size and sex offered on that page is the same listing.
Vendor coverage
75 vendor sites scanned daily, plus self-listed breeders. Private sales are not counted.
Live vs ever
Live listings are what is for sale today. The tier counts every seller seen since tracking began, with no cutoff date, so a species with seven listings today can still be Rare.

Rarity is in beta. It counts how many sellers have listed a species, not how many animals exist. Tiers are given to tarantulas only. It is not a conservation status and does not predict future scarcity.

Fire is the lowest in-stock ask we have recorded for that species, sex and life stage, per single animal, before shipping, with at least two shops in the comparison. A multi-animal pack never sets a record.
