Hello. Name of this walrus is "Neseyka" or "Neseika" (not "Neyeska"), that means "junior" in Nenets language. People of this nationality live on the peninsula of Yamal where Neseyka arrived from.
We were afraid that Neseyka may pursue and even injure her new neighbours because she is a walrus, and walruses are usually not so delicate and careful as other may want. But she appeared much cleverer... than us
Neseyka is the atlantic walrus, this subspecies is included to Red List of threatened animals of Russia. There is a law that threatened animals may be moved to another country only for a one year. But as far as I know the whole time of Neseyka's visit to Germany is about two years so you'll have enough time.
Well, we didn't do genetic tests or something like that, but peninsula of Yamal and Kara sea (where Neseyka arrived from) are in limits of area of O.r. rosmarus. Area of O.r. divergens is at a great distance to the east from this place. So Neseyka belongs to subspecies O.r. rosmarus until another information is proved.
By the way: I 've seen videos and read some articles in German and found many divergences . For instance Neseyka's weight is specified from 550 (correct or almost correct) to 800 (!) kg.
When people speak Neseyka's name they pronounce letter (sound) "S" as in German word "See" despite of it should be pronounced as in English word "see"
But Germans thought out interesting short name: "Nessi". In Russian we have another rules to make short and tender names, and Loch Ness is too far from us - so this version missed us.
I think it's not a weird law, only my English is weird
I meant that it is posible that animal will live in another country more than one year but mass of papers is valid only for a year. It was hard to make Neseyka's trip real, and it took a lot of time (several months - and not least because of she is a red-listed animal). Serious problem with papers next time may cause animal's return back until everything is good (extremely bad scenario), but I think everything will be fine.
Note: I'm not a lawyer, and I just tell you what I was told about this case.
