Advertisement I think it's likely that a good number of our pet spiders are not pure-blooded. (Some of our hobby species are known to be less pure than others.) However, in order to comply with the statute, you'd need to be able to document the hybrid lineage, which is difficult to do considering: We don't keep records of tarantula lineages. We generally don't even inquire. (In some cases, a buyer may know one parent's owner but probably knows nothing about the other parent or either parent's lineage.) We discourage people from deliberately creating hybrids or breeding questionable-looking tarantulas. We'd be talking out of both sides of our mouths if we said, "Hybrids are bad. Don't create hybrids, but all of these hobby Pokies should be legal, because they're hybrids."
