For the record more then 1 of both spider's and pin's have been found. I was sent a hatchling spider from a bush caught female. Just about all recessive morphs are found every season. I work with a "ball lord" in africa and i've seen so many single gene morph either be found in the bush or captive hatched from gravid females found in the bush. The only morphs I haven't seen are banana's, champagne's, and sentinel's. Just because we don't hear about these things doesn't mean it doesn't happen. The US isn't the only market and a lot of the guys in Africa sell things with out letting anyone else know and they get shipped all over the world.
They know what the morphs are worth they have access to the internet just like we do and they do keep anything crazy.
