I wonder why it is only now that this species is spreading in zoos, given its charisma, size, and endangered status? Maybe more institutions feel like the husbandry knowledge has advanced far enough to justify keeping them?
Hopefully the LA Zoo's new exhibit will be a great home for the species.
It is really too bad that LA has to handrear these cubs again. Much better conditions at other zoos - especially in Europe - make this unnessecary. Parents now regularly rear their cubs successfully, also in the presenece of older siblings (they learn most valuable parenting skills !)
Generaly, giant otters are becoming more common in zoos, because more and more follow the International Studbooks husbandry guidelines !
