    With those kind of numbers, and the infrequency of bringing in stranded wild individuals as founders, the MMTAG and participating institutions may have to decide to either import or phase-out. Or they could just manage them as a DERP and exhibit them whenever they're available. Either way, situation looks pretty bleak for building a sustainable population base.

    0.1 Shushu ("Chou Chou") from Kamogawa Sea World has been moved to SeaWorld San Diego

    Very excited to see the possibility of fourth-generation / third-generation captive-born pups from her in the future!

    Frankly speaking, I would prefer that Neseyka is Pacific walrus...

    Why is that? She could still breed with the pacific males as evident from the Quebec animals.

    You are right, but hybrids are much less valuable for zoo work. This is the only problem I think.

    # 71 TZFan - #77 callorhinus

    :) 2 of 2 females at Aquarium Du Quebec are pregnant, that's great!
    I'm particularly pleased about that Arnaliaq is pregnant. I think, this is the first proof, that Odobenus rosmarus divergens x Odobenus rosmarus rosmarus (Boris x Arnalique) is possible.
    In Germany, we've tried the same (1.0 Odinnadtsatyi (Odin) x 0.1 Neseyka). Odin really liked her and they definitely had sex, but unfortunately without success.
    Sorry Callorhinus - I see it positive. Each walrus-cub born in captivity is a success, and a hybrid might have unknown positive properties. Such an animal doesn't exist yet; we'll see!
    Callorhinus - Maybe, it'll work at your facility too with 1.0 Enurmin X 0.1 Neseyka. Try it! No one can or want's to release walrusses born in captivity into nature. And in zoos and aquariums such hybrids are noway "less valuable". I'm sure! Perhaps they'll have great features.

    Yes, looking forward for the long-awaited sensation :)

    You are probably right, but it would not be surprise for animals of the same species.

    I will agree with you in the case which is similar to one in Six Flags Discovery Kingdom, I mean hard work to make mating and pregnancy possible. But in our case hybrid calf is just calf who needs a place etc. It is even worse if it is a bull: zoo had to sell/exchange/loan it when it's time. I can easily imagine situation when European/American zoo, which wants to acquire male, will search for pure subspecies.
