Much like the owl, these are recent developments - although a lot of "Virginia Opossum" in the private trade are actually misidentified White-eared Opossum so it is quite possible the arrival at Vogelbush Eureka belongs to this taxon.
Conversely, this is one I deliberately omitted - as I have already told you, other than Moscow and one or two other major collections I haven't been counting Russian collections as European for the purposes of this thread.
Given the fact Vladivostok is on the border of North Korea, this applies doubly-so for said collection
